Parameter Description
CURVE
If the CURVE value is increased, the heat curve will become steeper; if the value is reduced, it
will become flatter and less heat will be supplied when it gets colder. Raise to increase indoor
temperatures, reduce to lower indoor temperatures. (The factory setting is 40 for radiator sys-
tems and 30 for floor heating.)
MIN
Lowest setpoint for supply temperature. (Normally 20°C.)
MAX Highest setpoint for supply temperature. (Caution - high supply line temperature may cause
damage to e.g. floors with floor heating.)
CURVE 5 Used to fine tune the heat curve at an outdoor temperature of +5°C.
CURVE 0
Used to fine tune the heat curve at an outdoor temperature of 0°C.
CURVE -5 Used to fine tune the heat curve at an outdoor temperature of -5°C.
HEAT STOP This function stops all production of heat when the outdoor temperature is equal to, or higher
than, the heat stop value currently set.
REDUCTION This function is not used in standard applications, but when used, this setting is used to set
desired reduction of ROOM value when the external control is active. (Also hot water produc-
tion may be affected when the external signal is active.)
