Why am I feeling too cold in my living room with my Daikin Heat Pump?
If you feel too cold, it might be because the desired room temperature is set too low. Try increasing the desired room temperature. Alternatively, increase the room temperature preset value or adjust the room temperature schedule. If the desired room temperature cannot be reached, increase the desired leaving water temperature in accordance with the heat emitter type.
Why is my Daikin Air Conditioner space not sufficiently heated at low outdoor temperatures?
If the space is not sufficiently heated at low outdoor temperatures, it may be because too much heat pump capacity is used for heating domestic hot water. Check that the “space heating priority status” has been enabled and increase the “space heating priority temperature” to activate backup heater operation at a higher outdoor temperature.
How to activate the backup heater operation in Daikin Air Conditioner?
To activate the backup heater operation: * Ensure the backup heater operation mode is enabled. * Check that the thermal protector of the backup heater has not been activated. If it has, check the water pressure, whether there is air in the system and perform air purge operation. Then, press the reset button in the switch box. * Increase the “equilibrium temperature” to activate the backup heater operation at a higher outdoor temperature.
What to do if water is coming out of the Daikin Air Conditioner relief valve with dirt?
If water coming out from the relief valve contains debris or dirt, open the valve until the discharged water does not contain dirt anymore. It is also recommended to flush the system and install an additional water filter, preferably a magnetic cyclone filter.
Why is my Daikin Air Conditioner compressor not starting?
The compressor might not start due to several reasons: * The unit may be starting outside of its operation range if the water temperature is too low. In this case, the unit uses the backup heater to reach the minimum water temperature (15°C). Ensure the power supply to the backup heater is correctly wired, the backup heater thermal protector is not activated, and the backup heater contactors are not broken. If the problem persists, contact your dealer. * The preferential kWh rate power supply settings and electrical connections may not match. Ensure they match the connections as explained in the manual. * The preferential kWh rate signal may have been sent by the electricity company. Wait for the power to return (2 hours max.).
What to do if the Daikin Air Conditioner pump is making noise?
If the pump is making noise, it could be due to: * Air in the system: Purge air manually or use the automatic air purge function. * Low water pressure at the pump inlet: Check that the water pressure is above 1 bar, the manometer is not broken, the expansion vessel is not broken, and the pre-pressure setting of the expansion vessel is correct.
Why does the Daikin Air Conditioner pressure relief valve open?
The pressure relief valve may open because: * The expansion vessel is broken: Replace the expansion vessel. * The water volume in the installation is too high: Ensure that the water volume in the installation is below the maximum allowed value.
What to do if the Daikin Air Conditioner water pressure relief valve leaks?
If the water pressure relief valve leaks, it might be because dirt is blocking the outlet. Check the valve by turning the red knob counterclockwise. If you do not hear a clacking sound or if water continues to run out of the unit, close both the water inlet and outlet shut-off valves and then contact your dealer.
What causes unusual high pressure at the tapping point in my Daikin Air Conditioner?
Unusually high pressure at the tapping point can be caused by a failing or blocked pressure relief valve. Flush and clean the complete tank, including the piping between the pressure relief valve and the cold water inlet, or replace the pressure relief valve.
What to do if Daikin Air Conditioner decoration panels are pushed away due to a swollen tank?
If decoration panels are pushed away due to a swollen tank, contact your local dealer.

This document provides a user reference guide for the Daikin Altherma Low Temperature Split system, covering models EHVH04SU18CB6W, EHVH08SU18CB6W, EHVH08SU26CB6W, EHVH11SU26CB6W, and EHVH16SU26CB6W. It details the operation, maintenance, and troubleshooting of the system, which is designed to heat spaces and produce domestic hot water.
The Daikin Altherma Low Temperature Split system is a heat pump designed for space heating and domestic hot water production. It operates by transferring heat from an outdoor unit to an indoor unit, which then distributes heat to the living space or heats water in a domestic hot water (DHW) tank. The system can be configured for various heating controls, including room thermostat control, leaving water temperature control, and external room thermostat control, depending on the system layout and installer settings.
For space heating, the system can operate in different modes, allowing users to set desired room temperatures or leaving water temperatures. The leaving water temperature is the temperature of the water sent to the heat emitters (e.g., underfloor heating, radiators). The system can adjust this temperature based on user settings or automatically in weather-dependent operation.
For domestic hot water, the system offers several modes: Reheat mode, Scheduled mode, and Scheduled + Reheat mode. In Reheat mode, the DHW tank continuously heats water to a set temperature. In Scheduled mode, hot water production follows a user-defined schedule, often optimized for off-peak electricity times. Scheduled + Reheat mode combines these, allowing scheduled heating with a reheat function to ensure a minimum amount of hot water is always available. The system also includes a DHW tank booster mode for immediate hot water production when needed, though this consumes extra energy.
The system's operation can be influenced by energy prices, allowing users to set fuel and electricity prices, including schedule timers for electricity, to optimize running costs. An incentive per kWh renewable energy can also be factored into these calculations.
The user interface provides intuitive control over the system's functions. It features buttons for navigation, status icons to indicate the system's current state, and a menu structure for configuring settings.
