CURVE +5 Local increase or reduction of CURVE at an outdoor temperature of +5°C. Shown in the
graph for CURVE.
0°C(range: -5°C /
5°C)
CURVE 0 Local increase or reduction of CURVE at an outdoor temperature of 0°C. Shown in the
graph for CURVE.
0°C(range: -5°C /
5°C)
CURVE -5 Local increase or reduction of CURVE at an outdoor temperature of -5°C. Shown in the
graph for CURVE.
0°C(range: -5°C /
5°C)
HEAT STOP Maximum outdoor temperature when heat production is permitted.
If HEAT STOP applies, the outdoor temperature must drop 3°C below the setting before
HEAT STOP stops.
17°C(range:
,
0°C / 40°C)
REDUCTION Only appears if the tariff control function has been activated. Lowering set room temper-
ature. Active at 10 kΩ connection at EVU input.
2°C(range: 1°C /
10°C)
TANK TEMP Displayed if buffer tank is active. Charges the buffer tank to the set temperature. AUTO
setting charges the tank to the supply line setpoint value.
AUTO(range:
AUTO, 30°C /
55°C)
OVERCHARGE Displayed if the buffer tank is active and TANK TEMP is set to AUTO. Charges the buffer
tank to supply line setpoint value + the value of OVERCHARGE.
0°C(range: 0°C /
5°C)
ROOM FACTOR Only displayed if an accessory Room temperature sensor is installed.
Determines how great an impact the room temperature is to have when calculating the
supply temperature. For under floor heating it is recommended that ROOM FACTOR is set
to 1, 2 or 3. For radiator heating it is recommended that ROOM FACTOR is set to 2, 3 or 4.
(0 = no impact, 4 = very large impact).
2(range: 0 / 4)
POOL (Expansion card) Only appears if POOL is selected. The temperature in the pool is controlled by a separate
sensor regardless of the heating and hot water system.
20°C(range:
,
5°C /40°C)
POOL HYSTERESIS (Ex-
pansion card)
Only appears if POOL is selected. The difference between the desired charge value (ad-
justable) and actual value to the pool sensor. Pool hysteresis does not affect the integral
value.
2°C(range: 1°C /
10°C)
8.3 Sub-menu HEAT CURVE 2
Only appears if shunt group sensor is connected and activated in menu SERVICE -> INSTALLATION - SYSTEM -> SHUNT GROUP.

CURVE 2 Calculated shunt group temperature at 0°C outdoor temperature. Shown as a graphic
curve. The curve will be limited by the set values of MIN and MAX.
40°C(range:
22°C / 56°C)
MIN Minimum permitted shunt group temperature, if the temperature for heat stop has not
been reached.
10°C(range:
10°C / 50°C)
MAX Maximum permitted shunt group temperature. 55°C(range:
15°C / 70°C)
8.4 Sub-menu TEMPERATURE
The history of different temperature measurements can be viewed by pressing the right arrow key. The graph shows the last 60 meas-
urement points for the set time interval (SERVICE -> INSTALLATION -> LOG TIME). In the event of an alarm, history stops being logged
until the alarm is reset by changing the operating mode to OFF.
