Room High Limit Setpoint
– This displays the calculated High Limit Setpoint for the room temperature. If the space
temperature goes above this value then the heating will be disabled until it
has dropped 1’C below it.
Origin
– this is the base temperature of the heating set point (flow temperature) when the outside air temperature is
at 20’C.
Typical settings for this depend on the system being used. For example:
Under
floor Heating Systems: 30’C
Radiators in a school: 20’C
Radiators in a care center: 30’C
Fan Convectors: 60’C (or the set minimum required of the convectors to run)
Space Frost Set point
– This is the set point during non-occupation at which the heating will be switched on. The
Heating will return to Auto when the space temperature has risen by 2’C
Room High Limit Offset
– This value is added to the Space Set point to set the Room High Limit Set point. Check
with the bill payer before increasing this value and ensure they are aware of the reasons why this needs to be
changed.
