Pump-kick function for solar collector
Pump-kick function for solar collector pump is set with parameter S6.8=1. If collector
temperature is higher as minimum collector temperature, the pump is activated each 15
minutes for 10 seconds. This way a realistic collector temperature is acquired. This setting
is used in case if collector sensor isn’t mounted directly into the collector body.
DOMESTIC HOT WATER CIRCULATION
The d. h. w. circulation pump is operating according to the time program for the d. h. w.
circulation - parameter P4.7. The pump is operating with running and standby intervals
which are set with parameters P4.8 and P4.9.
D. h. w. circulation on output R0 or R9
With parameter setting S1.11=2 (R0) or S1.12=3 (R9) output can be programmed for the
activation of d. h. w. circulation.
D. h. w. circulation with the use of sensor
If T1 or T8 sensor is free, it can be used to activate the d. h. w. circulation with parameter
S1.4=4 (for sensor T1) or S1.5=7 (for sensor T8).
The sensor needs to be installed on the exit pipe from the d. h. w. storage tank (hot pipe).
Whenever an immediate temperature rise for at least 5 K is detected, the d. h. w. circula-
tion pump is switched on for the time set with parameter P4.8.

REMOTE HEATING ACTIVATION
Setting the parameter S1.6=1 enables a remote activation of room heating and d. h. w.
warming with telephone controlled switch Telewarm G1-D or any other device with a poten-
tial-free control switch. Room heating according to the requested day time temperature and
d. h. w. warming are activated if a short circuit is detected on input T1, T6 or T8.

OPERATION OF HEATING SYSTEMS WITH TWO HEAT SOURCES
KXD controllers feature fully automatic operation of heating systems with two heat sources,
for example with solid and liquid fuel boiler. Systems can operate with or without a heat ac-
cumulator. The hydraulic connection of the two heat sources can be parallel or serial.
