Product detailed description
A digital thermostat for controlling heat sources with OpenTherm communication. PT55X is suitable for cascade boiler rooms. A great advantage is the possibility of expanding its functions by connecting the external MS1 fault-signalling module and the GST1 GSM module.
Advantages of the PT55X thermostat:
- option to connect external modules (not included with the PT55X - can be purchased separately!)
- option to set 9 weekly programs for CH (with six temperature changes per day)
- option to set a weekly program for DHW (with three time intervals per day)
- weather compensation control (choice of 60 heating curves)
- PI control
- option to connect an external (underfloor) sensor
- summer mode
- odd/even week selection
- simple control and programming
External modules:
1, GST1 module for controlling the thermostat by mobile phone
2, MS1 fault-signalling module (in the event of any error sent by the boiler via OT to the thermostat, the MS1 relay's idle contact closes, to which another light or acoustic device can be connected)
PT55X can be used for boilers communicating according to the OpenTherm protocol and meeting the given technical specifications.
