The
AURATON S14
electronic pump controller is also intended for
automatic control of the circulation pump (depending on the
temperature) in the hot domestic water (HDW) circuit.
The controller maintains constant temperature of water in a tank or in the
HDW circuit.
The controller has priority functions which prevent cooling down water
in the HDW tank.

5.1. Operation with the HDW over CH priority
switched on
If the HDW over CH priority function is switched on, then the pump in the
HDW circuit depends only on the setting and on the temperature
measured by the
SR3
sensor installed in the tank.
5.1.1. Settings range
Temperature (from 0°C to 99°C) is measured by the
SR3
sensor. The HDW
pump is controlled using the
OUT4
output. The settings range for the
HDW pump is equal to 10°C to 85°C, and the hysteresis (the temperature
difference between the start and the stop settings) is adjustable in the
range of 2°C to 10°C.
5.1.3. Manual mode - continuous operation
In order to manually switch on the circulating pump (regardless of the
current temperature at the SR3 (HDW) sensor), press the "
C
" button and
hold it for 3 seconds. The display will show the " ". If you wish to switch
off the HDW pump's manual operation, press the "
C
" button again and
hold it pressed for 3 seconds.
NOTE: If the temperature measured by the sensor (SR3) exceeds 85 °C,
the HDW pump will be switched off in order to prevent excessive
heating of hot water in the tank.
5.1.2. Programming of the HDW functions
When the " " button is pressed, the value of 50 °C (factory setting) starts
blinking. Use the "+" or "-" button to set the desired temperature.
Once the desired temperature value is set, it must be confirmed (do not
forget to do so) within 10 seconds by pressing the "
" button.
Otherwise, the changed value will not be saved and the controller will
return to the previous setting.
After the new value has been saved, the controller leaves the settings
status and switches to normal operation (the temperature setting stops
blinking). The controller starts the HDW pump (
OUT4
) if the temperature
measured by the
SR3
sensor exceeds the set temperature value by the
hysteresis value and stops the pump when the temperature drops below
the hysteresis value.
