P07
00..02
= No function is associated
03
= This is an input contact for CH request (e.g. trigger phone).
When contact CN2 is closed and Room Thermostat (RT) requiring heat switches burner on.
Note:
verify heating mode is enabled (winter or heat only mode)
04
= This is an input contact for Low Temperature Thermostat (e.g. floor heating system).
When Low Temperature Thermostat connected on CN2 cuts out, burner switches off and display shows
E178
anomaly.
Note:
verify heating mode is enabled (winter or heat only mode)
05
= This is an input contact for external DHW recirculation pump. When contact CN2 is closed the pump
runs for a specific period.
To enable input it is necessary to set parameter
P04 or P05 = 08
and
P69 = 05
.
Pump will run at
P19
minutes (Summer/Winter mode or Only Winter mode) or
P19/2
minutes (only
Summer mode).

Heating set-point setting OT / RT (Open Therm / Room Thermostat 120V~)
00
= with Remote Control (RC) connected, temperature request is RC set-point
01
= Temperature Request is highest set point between RC and PCB
02
= Temperature request is RU setpoint. The RT enable the gas boiler operates
