Thermostat with OpenTherm communication PT52

Product detailed description

PT52 thermostat features:

Room thermostat for controlling heat sources with OpenTherm (OT+) communication (= data communication system between the boiler and the thermostat).

Advantages of the PT52 thermostat:

• large BACKLIT display and simple control
  
• intuitive navigation of settings in the selected language (CZ/PL/EN/DE/RU/SVK)
  
• 9 weekly programs for heating (with 6 temperature changes per day)
• 1 weekly program for domestic hot water (with three time intervals per day)
• weather-compensated (equithermal) control*
• weather-compensated control with correction according to indoor temperature*
• building influence constant
• PI control
• early heating start-up with advance time setting
• selection of boiler type (e.g. Thermona, Dakon, Quantum, Geminox, Ferroli, Viessmann and others)
• quick change of the desired heating and domestic hot water temperature
• holiday mode
• summer mode
• current temperature correction
• key lock
• automatic switch to summer/winter time
• display of information sent by the boiler via the OT line (current heating temperature, calculated heating temperature, output in %, flow rate, return temperature and outdoor temperature)
• total operating hours for both heating and domestic hot water
• frost protection
• clock backup for approx. 8 hours

PT52 can be used for boilers communicating according to the OpenTherm protocol and meeting the given technical specifications.

*WEATHER-COMPENSATED CONTROL SETTINGS:

We have prepared a clear graphical display of weather compensation curves for you. By selecting the curve number and offset, you optimize the boiler's operation and achieve the required heating water temperature value at different outdoor temperatures
