Heating circuit controller

AVERAGE of outdoor temperature

Sometimes, fluctuations in outdoor temperature may even not be desirable in calculation of flow

temperature or when determining the disconnection of the heating pump. Therefore, a separate calcu-
lation of the mean is available for the outdoor temperature to calculate the heating curve and the
disconnection of the pump. The following entries are found in this submenu:

HTG CIRC.1

for flow control:

Aver time: 10 min

The average outdoor temperature is calculated for 10 minutes
for the flow

T.outs.av.c: 13.6 °C

The current outdoor temperature average is 13.6°C

for shutdown:

Aver time: 30 min

The average outdoor temperature is calculated for 30 minutes
for switching off

T.ou.av.off: 13.8 °C

The current outdoor temperature average is 13.8°C

SHUTDOWN CONDITIONS and mixer behaviour

The controller allows the following switch-off conditions for the heating circuit pump:

if T.room
ACT > SET ? no
Hysteresis: 1.0 K

when the desired room temperature has been reached

If T.flow
SET < MIN ? yes
Hysteresis: 2.0 K

when the flow temperature falls below the lower limit T.FlowMIN

If T.outs.
Av.off> MAX ? no

T.outs.MAX: 20 °C
Hysteresis: 2.0 K

when the average outdoor temperature T.Out.MAX exceeds a

set value in the heating or lowering mode

If setback mode
and T.outside
ACT > MIN. ? no

T.outs.MIN: 5 °C
Hysteresis: 2.0 K

when the outdoor temperature T.Out exceeds a set value in the

lowering mode

If T.flow
ACT > MAX ? no

when the flow temperature is larger than T.FlowMAX (settings in

the heat curve) plus a fixed hysteresis of 3K, reactivation if
T.FlowACT. < T.FlowMAX

If heating circ. OFF
MIXER: close

Mixer behaviour:

In addition, in this menu you can determine

how the mixer is to respond once the pump has been switched
off (

close, open, unchanged, (continue to) control

).

If mixer enable is "OFF" the mixer remains stationary in the last

position it took up (Status Mixer: OFF).

The hystereses of the switch-off conditions generally have an

increasing

effect.

As both the outdoor temperature and the room temperature are taken into consideration when the set

flow temperature is calculated (provided a sensor is used), the best method is to switch off under the
limit T.flow MIN.
