TANK TEMP Displayed if buffer tank is active. Charges the buf-

fer tank to the set temperature. AUTO setting

charges the tank to the supply line setpoint value.

AUTO

(range:

30°C / 55°C)

OVER-

CHARGE

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 OVER-

CHARGE.

0°C

(range: 0°C /

5°C)

ROOM FAC-

TOR

Only displayed if an accessory Room temperature

sensor is installed.

Determines how great an impact the room tem-

perature is to have when calculating the supply

temperature. For under floor heating it is recom-

mended 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.

2

(range: 0 / 4)

(0 = no

impact,

4 = very large

impact)

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 HYSTE-

RESIS (Expan-

sion card)

Only appears if POOL is selected. The difference

between the desired charge value (adjustable) and

actual value to the pool sensor. Pool hysteresis

does not affect the integral value.

0°C

(range: 5°C /

40°C)
