10.4 Enable/disable keep hot facility by Open Therm room thermostat.
It is possible to enable and disable the keep hot facility of the boiler by using an Open Therm
room thermostat. For this the boiler needs to be set in Eco mode : ( LED on).
Also the parameter o. needs to be set to 0. In this setting the adaptive behaviour of the
boiler (see § 4.4 ) is disabled.
The Open Therm room thermostat will now enable or disable the keep hot facility
(provided that the room thermostat supports this function)
10.5 Weather– compensation adjustment
When an external sensor is connected the supply temperature is adjusted automatically
depending on the outside temperature, in accordance with the heating line set. The
maximum supply temperature (Tmax) is set via the main display. If desired, the heating
line can be changed in the parameter list. See § 10.3.
