Wireless Thermostat C3RF

Description

Non-programmable digital room thermostat with Logictherm C3 RF radio transmission for controlling a heater or air conditioner

C3RF is suitable for controlling a heater or air conditioner, being compatible with most thermal power plants in Romania and the EU, regardless of the control voltage (24 V or 230 V).
The Logictherm C3RF thermostat is mobile, does not require a wired electrical connection to the boiler, it is a transmitter that sends radio frequency signals to the receiver (a fixed module in direct connection with the heating boiler). The receiver receives the signals from the thermostat and commands the boiler to be switched on or off via the electrical cable connected between the receiver and the boiler.
The thermostat (transmitter) and receiver are paired. The transmitter thermostat and receiver are set at the factory to work on the same frequency and have the same address code.
To save battery power and extend battery life, the thermostat does not constantly emit signals, but sends commands to the receiver with a certain frequency.
The mobility of the wireless thermostat has the following advantages: it does not require the laying of an electric cable, it avoids the disturbance in the building; allows to find the optimal location; can be moved during the day, for example, day in the living room, evening in the bedroom.
Range = 50 m in open space, and about 30 m in a building, being influenced by the structure of the building. The range is much shorter if the waves encounter metal structures, reinforced concrete, etc.
If the mains supply voltage is interrupted, the receiver will command the boiler to be switched off, which cannot operate in the absence of electricity anyway. After the mains voltage returns, the thermostat and receiver will continue running the prescribed program after a few minutes.
The thermostat can be used in its holder or mounted on the wall.
Switching sensitivity is the difference between the set temperature and the temperature at which the thermostat switches on / off the boiler. The sensitivity of the thermostat is ± 0.2 ° C.
The display accuracy is ± 0.5 ° C.
Pump anti-lock function. In order to prevent the pump from stalling at 0 and 00 minutes, the thermostat commands the boiler to start for one minute. The command is given only if the thermostat has not given a start command for 24 hours.
