9.12 Function of pressure switch – Effect on pump and heater
Gala-Kool Pro distinguishes between two heating phases:
A
-
Heating-up phase
- programme step "H“
B
-
Further heating phase
- during the main circulation (n34 or n54 and n74).
During the heating-up phase, the water is heated to the temperature set (the display
shows the temperature measured by sensor 1 instead of the programme stage). The
next programme stage then follows. The heating-up time is, however, limited by an
adjustable timeout. Once the time has expired the control unit switches to the next
programme stage. The completion of washing is followed by a corresponding fault
report.
During the following further heating phase, the circulating washing solution is main-
tained at the further heating temperature that has been set.
NB:
If a second sensor has been configured as a washing sensor, temperature regulation
and the display switch over to the second sensor.
Heater start delay
Depending on the system layout, a start delay for the heater can be set. This applies
only at the beginning of the heating-up phase (depending on whether this starts in
programme stage “D2" or “H” .
)
This delay can be used to prevent the system switching on to the next programme
stage too soon ...

if pre-heated water e.g. from a boiler is cooled down by the cold walls of the
tank and needs to be reheated, or
... if, as a result of pre-set pump venting, the pressure switch triggers and the
heater is switched off (see also the sections “Pressure switch” and “Pump
venting”).

A pressure switch fitted to the washing circuit can protect the pump and heater from
damage.
Protection of the cleaning pump
Parameter [r11] can be used to set the length of time during which there may be no
pressure in the washing line before washing is stopped. This prevents the washing
pump being damaged by running dry.
Protection of heater
Parameter [r38] can be used to set the length of time during which there may be no
pressure in the washing line before the heater is switched off. Washing continues
nevertheless.
This prevents heater burn-out.
