The COMPUTHERM T32 type switched-mode room thermostat is suitable to regulate the overwhelming majority of boilers and air conditioners available in Hungary. It can be easily connected to any gas boiler having a two-wire thermostat connection point and to any air conditioning apparatus or electrical apparatus, regardless of whether they have a 24 V or 230 V control circuit.
Temperature can be measured and set at digital display more precisely as compared to simple, conventional thermostats. In heating mode, the thermostat switches the boiler or any other appliances on below and off above the adjusted temperature, respectively, and contributes to reduce energy costs while maintaining comfort. In cooling mode it switches the opposite way.
The simultaneous use of several COMPUTHERM room thermostats and one COMPUTHERM Q4Z zone controller provides the possibility for the thermostats to also control a pump or a zone valve in addition to starting the heater or cooler. This way it is easy to divide a heating/cooling system into zones, thanks to which the heating/cooling of each room can be controlled separately,thus greatly increasing comfort. Furthermore, the zoning of the heating/cooling system will greatly contribute to the reduction of energy costs, as due to this only those rooms will be heated/cooled at any time where it is required.
It is reasonable to locate it in a room used regularly or for many hours per day so that it is in the direction of natural ventilation in the room but protected from drought or extreme heat (e.g. direct sunlight, refrigerator, chimney, etc). Do not use in wet, chemically aggressive or dusty environments. Its optimal location is 0.75 – 1.5 m above floor level.
IMPORTANT WARNING: If the radiator valves in your flat are equipped with a thermostatic head, adjust it to maximum temperature or replace the thermostatic head of the radiator valve with a manual control knob in the room where the room thermostat is to be located, otherwise the thermostatic head may disturb the temperature control of the flat.
WARNING: The device must be installed and connected by a qualified professional!
Before installing, make sure that neither the thermostat nor the device to be controlled is connected to the 230 V mains voltage. Modifying the thermostat can cause electric shock or product failure.
To install and connect the thermostat you should perform the following steps:
If you would like to operate an old boiler or any other device that has no connection points for thermostats, then the NO and COM connection points of the thermostat should be connected to the mains cable of the device, similarly as a switch would be connected.
ATTENTION
Always consider the load ability of the thermostat and follow the manufacturer’s instructions of the heating or cooling equipment. The device must be installed and connected by a qualified professional. The voltage appearing at terminals NO and COM depends only on the system being controlled, therefore the dimensions of the wires are determined by the type of the device to be controlled. The length of the wire is of no significance.
To put the thermostat into operation you should perform the following steps:
Warning: Alkaline batteries may only be used for this appliance. Carbon-zinc batteries known as durable or long life batteries and chargeable accumulators are not suitable for the operation of this appliance. The
You can calibrate the thermometer of the appliance (to correct the measured temperature). To enter the calibration menu, in the OFF state of the thermostat, press and hold the
You can have the possibility to easily switch between heating (factory setting) and cooling modes. The output terminals NO and COM of the thermostat are closed below the set temperature in heating mode, and they are closed above the set temperature in cooling mode (taking the switching sensitivity into account). The closed position of the NO and COM connection points of the output relay is indicated by the appearance of the icon
To enter the switching mode menu, in the OFF state of the thermostat, press and hold the
With the temperature adjustment buttons (
Depending on the change in the room and set temperature the thermostat controls (turns on or off) the heating/cooling system connected thereto. By default, the NO and COM contact pairs of the relay are open. The closed position of the NO and COM connection points of the output relay is indicated by the appearance of the icon on the display of the apparatus both in heating and cooling modes. From both a comfort and an energy-efficiency point of view, it is recommended to activate more than one switch for each day. Furthermore, it is advised that a comfort temperature is used only those times, when the room or building is in use since every 1 °C decrease of temperature saves approximately 6% energy during a heating season.
The average lifetime of the batteries is 1 year. The thermostat indicates the battery charge level (e.g.

RESETTING THE THERMOSTAT TO ITS FACTORY DEFAULT SETTINGS
You can return all settings of the apparatus (set temperature, temperature calibration and heating/cooling mode) to their defaults. To restore factory settings press the
