Setpt Setpoint
The current Comfort setpoint is the setpoint selected with the remote setpoint ad-
juster.
Although the remote setpoint adjuster predefines the Comfort setpoint, a fixed Comfort
setpoint ”Heating” must be entered via
Main menu > Heating circuit
> Room setpoints
. From
the difference between the fixed Comfort setpoint for “Heating“ and the setting made
with the remote setpoint adjuster, the current Comfort setpoint for ”Cooling“ can be
calculated:
Comfort setpoint “Cooling“ + (“Remote setpoint” minus Comfort setpoint “Heating“)
The RMK770 controller has no Comfort setpoint for “Cooling“. The impact on the Com-
fort setpoint for “Cooling“ as described above is only possible in connection with a room
control combination. For more detailed information, refer to subsection 10.10.3 “Room
control combination“.
The setpoint shifts are limited by the setpoints for Protection (also refer to the diagram
above).
The Precomfort setpoints are shifted also:
Hence, the current Precomfort setpoint for “Heating“ is calculated as follows:
Precomfort setpoint “Heating“ + (“Remote setpoint“ minus Comfort setpoint “Heating“)
And the current Precomfort setpoint for “Cooling“:
Precomfort setpoint “Cooling“ + (“Remote setpoint“ minus Comfort setpoint “Heating“)
The information given in paragraph ”Impact on the Comfort setpoint“ also applies
analogously to the Precomfort setpoint.
