Description of product
Properties PT55:
Digital thermostat for operation of heat sources with the OpenTherm communication (= system
of data communication between the boiler and thermostat).
Advantages PT55:
- option nine week programs for CH (with six temperature changes per day)
- option one weekly program for DHW (with three time intervals per day)
- equithermal control
- equithermal control with correction according to the internal temperature
- constant of the building influence
- PI control
- premature activation of the heating (PZT)
- possibility of connection of an external sensor (CT01-10k C/S/P)
- summer mode
- choice even/odd week
- simple to controlling and programming
PT55 can be used for the boiler according to the protocol OpenTherm communicating and meeting the technical specifications.
