5.8 Heating function "Heating enable"
An additional temperature sensor is always
required for heating control.
The temperature of the swimming pool water is measured using
the integrated temperature measurement of the chlorine sensor for
compensation of the chlorine measurement. This temperature
measurement can also be used to control a valve or pump for
heating purposes. Connection of the valve or pump to the terminals
[P2] ... [P7] of the F module. The setpoints and switching behaviour
are set in the operating menu of the Dulcomarin
®
II under
[Parameter].
To make possible resource saving operation, a
‘Solar priority
connection’ can be activated. If the solar temperature is about 5 °C
higher that the swimming pool water temperature, then the solar
pump or the solenoid valve is, as necessary, activated and the
solar energy used. If the water temperature in the swimming pool
water is lower than the desired setpoint, then the normal heater is
activated. This control mechanism is implemented until the solar
temperature falls below the 5 °C difference with the swimming pool
water. It is then possible to heat using the other energy carriers via
a heat exchanger, if this is required. Connection of the F module
takes place at the terminals
[P2] ... [P7]
The heating system must be activated in the M module so that it
can be set up. The set-up and selection takes place identically to
all other modules of the Dulcomarin
®
II. Under
[RTD (temperature)]
in the M module the parameters,
[], [PT100/1000] or
[PT100/TempCL] can be freely adjusted. If the [PT100/1000]
sensor is activated, the set temperature can be controlled using a
heat exchanger. If
[PT 100/TempCL] is activated, the control ini‐
tially controls, provided there is a sufficiently high temperature in
the solar absorber, the heating of the swimming pool using the
solar input and only once the difference temperature has fallen
below 5°, does the control switch the solar absorber off or switch
over to the control variable
[Enable heating]. If no output is avail‐
able for
[Enable heating], then heating of the pool water is only via
the solar absorber (solar energy). If the circulation timer is not
active and the sun heats the solar absorber above a 5 °C differ‐
ence, then circulation starts automatically in order to use the
energy input and avoid overheating of the solar absorber.
