Caution

This thermostat should be installed by trained technicians only. Adhere to all

local and national codes and ordinances. Disconnect all power to the system

before installing, removing, or cleaning.

The thermostat wiring is factory installed by the OEM (Original Equipment

Manufacturer). RV Products suggests the thermostat wiring be a minimum of

18 gauge. The thermostat is intended for use with a 12 VDC control circuit that

does not exceed 1 amp. The thermostat is equipped with a replaceable 2 amp

fuse located on the base of the thermostat. The fuse is designed to “open” if

the circuit is mis-wired or if there is a short in the system. Before replacing the

fuse, the cause of the failure must be located and corrected.

Application

Operation

The display indicates the mode and the room temperature. When the mode

button is pressed once, the thermostat will wake. If your thermostat is equipped

with a backlight, the backlight will illuminate. When the mode button

is pressed again, the mode will change. Press the or button to wake the

thermostat; the set temperature will display and the mode will ﬂash. Press the

or button again to change the set temperature. The thermostat will return

to sleep mode after 5 seconds if no button is pressed.

There is a three minute anti-short cycle for cooling. After the cooling system

has been de-energized, the system will not energize again for three minutes,

to protect your compressor. To bypass the anti-short cycle, change the mode

to OFF.

Note: Operating your cooling system when the outdoor temperature is

below 50°F can cause damage to your cooling equipment.

Pairing the Thermostat

A. THERMOSTAT LOCATION

This thermostat is a sensitive instrument. For accurate temperature control and

comfort, the following considerations should be taken into account:

1. Locate the thermostat on an inside wall about ﬁve feet

above the ﬂoor. Pick a dry area where air circulation is good.

2. Do not install thermostat where there are unusual heating

conditions, such as direct sunlight, near heat producing

appliances (televisions, radio, wall lamp, etc.), or a furnace

or air conditioner supply register.

B. INSTALLING THE THERMOSTAT

1. Place mounting screw template against the wall where

thermostat will be mounted.

2. Using supplied screws, mount the template to the wall.

3. Remove plastic from between mounting screws.

4. Connect thermostat wiring to motorcoach wiring.

5. Place thermostat on mounting screws and gently push the thermostat down

to lock the thermostat onto mounting screws.

6. Turn on power to the thermostat.

Installation

ELECTRICAL SHOCK HAZARD – Turn off power at the main service

panel by removing the fuse or switching the appropriate circuit

breaker to the Off position before removing the existing thermostat.

This document describes the installation, operation, and application of a thermostat, specifically the 9430354, 9430355, 9430357, and 9430358 models, which are designed for RV use. The thermostat is a sensitive instrument intended for accurate temperature control and comfort within an RV environment. It supports both cool-only and heat/cool functionalities, with specific models designated for each.

Function Description

The thermostat's primary function is to regulate the temperature within an RV by controlling the air conditioning and heating systems. It displays the current mode (e.g., cooling, heating, fan) and the room temperature. Users can adjust the set temperature and switch between different operating modes. The device incorporates a three-minute anti-short cycle for cooling, which protects the compressor by preventing it from re-energizing too quickly after being de-energized. This safety feature can be bypassed by changing the mode to OFF. The thermostat is designed to operate with a 12 VDC control circuit, not exceeding 1 amp. It includes a replaceable 2 amp fuse to protect against mis-wiring or system shorts.

Usage Features

The thermostat features a digital display that shows the current mode and room temperature. To activate the thermostat, users press the mode button once, which also illuminates the backlight if equipped. Subsequent presses of the mode button cycle through available modes. The up or down arrow buttons are used to wake the thermostat, display the set temperature (which will flash), and then adjust the set temperature. After five seconds of inactivity, the thermostat returns to sleep mode.

The thermostat can be controlled directly via its physical buttons or remotely through the RV Climate app, available on Google Play and Apple App stores. To pair the thermostat with a mobile device, users download the app, select "ADD NEW THERMOSTAT," and then simultaneously hold the Up and Down buttons on the thermostat to enter pairing mode. The app will prompt for a 6-digit ID from the thermostat to complete the pairing process. Once connected, the thermostat reverts to the main screen, and users can slide the screen left to access additional settings. Within the app, users can assign a custom name or description to the thermostat (up to 7 characters), select "SET" to save changes, and control the thermostat's temperature and mode settings. The app also allows for pairing additional thermostats, with a maximum of three units per individual phone, and managing previously paired thermostats, including the option to remove them. Each thermostat can be connected to a maximum of four individual phones; subsequent connections will automatically delete the oldest ones.

The thermostat also supports a Fahrenheit/Celsius toggle. Holding the mode button down for five seconds will switch the temperature unit. The backlight automatically turns off after five seconds of inactivity.

Maintenance Features

Installation of the thermostat should be performed by trained technicians, adhering to all local and national codes and ordinances. Before any installation, removal, or cleaning, it is crucial to disconnect power at the main service panel by removing the fuse or switching the circuit breaker to the Off position to prevent electrical shock.

For accurate temperature control, the thermostat should be located on an inside wall, approximately five feet above the floor, in a dry area with good air circulation. It should not be installed near direct sunlight, heat-producing appliances (like televisions, radios, or wall lamps), or near furnace/air conditioner supply registers, as these can create unusual heating conditions that affect temperature readings.

The thermostat wiring is factory installed by the OEM, and RV Products recommends using a minimum of 18 gauge wiring. If the fuse blows, it is essential to identify and correct the cause of the failure before replacing the fuse. Operating the cooling system when the outdoor temperature is below 50°F can cause damage to the cooling equipment, so this should be avoided.

The device complies with part 15 of the FCC Rules, ensuring that it does not cause harmful interference and accepts any interference received. The equipment has been tested and found to comply with Class A digital device limits, providing reasonable protection against harmful interference in a commercial environment. While designed for commercial use, operation in a residential area may require the user to correct any interference at their own expense.
