8.3.1 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 §
8.1.2 ) is disabled.
The Open Therm room thermostat will now enable or disable the keep hot facility (provided
that the room thermostat supports this function)
8.3.2 Summer mode.
When parameter q is set to a value unlike 0 it is possible to activate summer mode. During
Summer mode a request for Central Heating will be ignored. This mode does not affect the
delivery of DHW.
Summer mode can be activated by pressing the on/off button until the text, corresponding
with the setting of parameter q appears in the display,
Pressing the on/off button again will end the summer mode and set the boiler in stand-by
modus (sequence is off/on/summer/off ..etc).
