The Dimplex Monterey (MFPE) is an electric fixed local space heater designed for normal domestic household use, offering a range of features for efficient and flexible heating control. It is intended for wall mounting and should be installed in an upright position, adhering to specified minimum clearances. The heater is splash-proof to IP24, making it suitable for various indoor environments.

Function Description

The primary function of the Dimplex Monterey is to provide space heating with precise temperature control. It operates using a digitally controlled electronic thermostat, accurate to ±0.2°C, ensuring consistent room temperatures. The heater offers several operating modes, including various timer modes and continuous heat modes, to suit different user needs and schedules.

Usage Features

The Dimplex Monterey boasts advanced controls with capacitive sense technology, providing total flexibility in heating management. The user interface, located on top of the heater, consists of a display screen and six touch-sensitive buttons: Display Screen, 'Menu' Button, 'Back' Button, 'Up and Down' Arrows, 'Enter' Button, and 'Advance' Button.

First Time Power-On: Upon initial power-on, a setup wizard guides the user through setting the time, date, daylight savings time, and sound preferences. The heater then defaults to the 'Out All Day' Timer Mode on the Home Screen.

Home Screen: The Home Screen displays the current target temperature (setpoint) and the active mode of operation. It also indicates when the 'Advance' function is in use and shows 'Heating On' when the heater is actively trying to reach or maintain the room temperature, or 'Heating Off' otherwise. The display will 'sleep' after a period of inactivity but the heater remains active in its set mode.

Temperature Control: The heater's adjustable thermostat allows room temperature to be controlled within a range of 7°C to 30°C, with 21°C being a common comfortable setting. The screen color changes from deep blue to bright red based on the selected temperature, providing a visual cue.

Timer Modes: These modes are designed for efficient operation with predictable heat demand.

7 Day Programmable User Timer: Allows users to set up to four 'Heating On' time periods and target temperatures for each day of the week.
Out All Day: A default timer mode with specific 'Heating On' periods.
Home All Day: Another default timer mode with predefined 'Heating On' periods.
Away Mode: Temporarily overrides the active mode, maintaining a minimum room temperature (default 7°C for frost protection) until a specified return date and time. This is useful for short absences or holidays, ensuring heating resumes automatically upon return. The 'Back' button can be used to end Away Mode early.
Modifying Timer Modes: Users can modify the 'Heating On' times and target temperatures for each period within the User Timer, Home All Day, and Out All Day modes. The 'Advance' button facilitates copying and pasting settings between individual heating periods or entire days, saving time during configuration.
Adaptive Start: When enabled, this predictive function pre-heats the room to achieve the target temperature by the start of the 'Heating On' period, rather than beginning to heat at the start time. This feature learns the room's heating characteristics and adjusts daily. It is crucial that all heaters in a multi-heater room have Adaptive Start enabled to prevent inefficient heating.

Continuous Heat Modes: These modes provide a constant 'Heating On' period until manually changed.

Manual: Defaults to 21°C, adjustable between 19-30°C from the Home Screen.
Eco: Defaults to 18°C, adjustable between 8-18°C.
Frost Protect: Defaults to 7°C and is not user-definable, ensuring the room temperature does not fall below freezing.

Other Functions:

Boost Function: Provides a temporary 'Boost' of heat, activatable at any time in any Timer or Continuous heat mode, even if 'Advance' is active. Users can set a 'Boost Temp' (target temperature) and 'Boost Time' (duration countdown), with default values configurable in the Settings Menu. The 'Back' button can end Boost early.
Advance Function: Used exclusively in Timer Modes, this function temporarily alters the timer schedule. It allows a 'Heating On' period to begin or end early, useful for unexpected presence or absence from home.
Setback Settings: A function that modifies Timer Mode operation by overriding any 'Heating Off' period to maintain a constant temperature between 7°C and 18°C. This prevents the room temperature from dropping too low when there is no demand for heat.
Open Window Detection: A global setting that can interrupt any active mode. When enabled, the heater switches to a 'Heating Off' state if it detects an open window in the room, helping to conserve energy. This feature can be disabled if it activates in error due to drafty environments or an undersized heater.
Sound: Allows enabling or disabling audio feedback when buttons are pressed.
Comms (Communications): Enables or disables wireless connectivity features, displaying a list of available communication methods.

Product Locks: These features restrict access to the heater's controller functions.

Child Lock: A full product lock without a PIN code, toggled on/off by pressing and holding the 'Back' and 'Enter' buttons for three seconds.
PIN Lock: Disables all UI buttons except the 'Menu' button, unless 'Advance' has been enabled as an exception. Within the Main Menu, 'Boost' and 'Unlock' are selectable. 'Unlock' prompts for a 4-digit PIN.
PIN Lock Exceptions: Allows 'Advance' and 'Boost' functions to be enabled or disabled even when PIN Lock is active. Users can configure whether to allow activation of 'Advance' via its button, 'Boost' via the hotkey, and modification of 'Boost Temperature' and 'Boost Duration'.

Advanced Settings: These settings offer significant changes to the heater's operation and are recommended for modification only by trained professionals due to the risk of user error.

Temp Units (Temperature Units): Defines whether temperature units are displayed in °C or °F.
Room Temp (Temperature) Offset: Allows manual adjustment of the electronic thermostat reading by +/-3.0°C.
Factory Reset: Restores all settings to their default factory values.

Maintenance Features

Cleaning: Before cleaning, the heater must be disconnected from the electrical supply and allowed to cool. The exterior can be cleaned with a soft, dry cloth; abrasive cleaning powders or furniture polish should be avoided to prevent surface damage. For thorough cleaning or redecoration, the heater can be unhinged from its wall bracket by depressing the latch on both brackets and hinging it forward.

Battery Replacement: The product is fitted with a replaceable coin cell battery for the real-time clock, with a life expectancy of over 5 years. To replace the battery, the heater must be isolated from the electricity supply. The battery module is accessed by unhinging the heater from the wall, sliding a catch, and pulling the module from the controls. After replacing the battery, the module slides back into place, ensuring the clip is engaged. The old battery should be disposed of appropriately.

RF Module Installation: The heater is capable of connecting to Dimplex Control, which requires additional hardware, specifically an RF module. To install the RF module, the heater is unhinged from the wall, the battery module is located and removed, and the RF module replaces the battery tray. After installation, the product is powered on, and RF communications are enabled via the 'Comms' settings menu.

Overheating Protection: For safety, the heater is equipped with a thermal cut-out. In the event of overheating, this cut-out automatically cuts power to the heater. Once cooled, it resets automatically. The display screen may flash red to indicate overheating. To reset the display, the obstruction causing overheating must be removed, and the 'Enter' button held for 10 seconds.

Troubleshooting (Error Codes): The heater provides error codes to assist in diagnosing issues. These codes cover various categories such as Thermistor Failures (e.g., Room thermistor error), Excessive Temperatures (e.g., Overheat), Internal Failures (e.g., Element failure), User-Related Errors (e.g., Open window detection failure, Timeloss failure), and IoT Related Errors (e.g., error between heater and RF module).

General Safety and Important Notes:

The wall bracket supplied must be used, and the heater must be installed in the correct orientation.
Do not cover or obstruct the heater, as this can cause overheating and fire risk.
The surfaces of the heater can become hot, requiring particular attention when children or vulnerable people are present.
Servicing and repairs should only be undertaken by approved service agents using manufacturer-approved spare parts.
Household dust, lit cigarettes, candles, and oil burners can cause soot deposits on and around the heater, which is not a fault of the heater.
The heater's mains power lead must not be damaged; if it is, it must be replaced by an installer or approved service partner.
The electrical installation must be carried out by a qualified electrician in accordance with current wiring regulations.
The heater must not be connected to the electricity supply via an external switching device (e.g., a timer) or a circuit regularly switched on and off by the utility supplier, as this could inadvertently reset the thermal cut-off and create a fire hazard.
Cables/flexes supplied with the product must not be extended.
During initial heat-up, some odor may be emitted due to new materials; this is normal and will dissipate with good ventilation.
The heater may produce noise during operation due to the expansion and contraction of the element, which is normal.
If the heater fails to operate, it may be due to the room temperature being higher than the thermostat setting.
The product contains a replaceable battery, and packaging (EPS) should be disposed of responsibly as it can be a choking hazard for children.
