5.1 Operation with deactivated priority of D.H.W.
over C.H.
Operation with deactivated priority of D.H.W. over C.H.
If the priority of D.H.W. over C.H. is deactivated, the start of
the pump in ten domestic hot water system depends only
on the setting and the temperature on the
SR3 sensor
which is installed in they storage vessel.
5.1.1) Settings range
The temperature (from 0oC do 99oC) is measured by the
SR3 sensor. The C.H. pump is controlled by means of the
OUT 4 output.
The three-way valve or the other C.H. pump are controlled
by means of the OUT 3 output. The settings range for the
D.H.W. pump is 10oC do 90oC. the hysteresis (temperature
difference between the activation and deactivation) is 3oC.
5.1.2) Programming the D.H.W. functions
Press once briefly the “ C ’” button - the factory setting 60oC
will start to blink. Then use the “ + ” or “ - “ buttons to set the
required temperature.
confirm by pressing “ OK ” within 10 seconds. Otherwise,
the new set value will not be stored in the memory and the
controller will return to the previous setting. When new
settings are stored in the memory, the controller exits the
settings mode and enter the normal operation mode (the
blinking of the temperature settings stops).
The controller will deactivate the D.H.W. pump (
OUT4
) if
the temperature on the SR3 sensor exceeds the set value
by 1oC and will activate the pump if the temperature drops
by 2oC below the setting.
5.1.3) Manual operation - continuous
To activate the C.H. pump manually (irrespective of the
temperature on the SR3 D.H.W. sensor), press and hold
the “
OK ” button and briefly depress the button “ C ”. The
hand symbol will appear on the display. To switch off
the D.H.W. pump manually, again press and hold the “OK”
button and briefly depress the button “
C ”.
NOTE : If the temperature on the T3 sensor (RS3) exceeds
90oC, the D.H.W. pump will switch off, preventing
excessive temperature of the water in the tank.
