7.4 Alarms sound
Option to enable/disable the alarm signal.
7.5 Pump anti-stop
Function to prevent " stagnation " of the built-in circulation pump. The function also works in
"standby" mode. The controller will start the circulation pump according to the following
parameters.
7.5.1 Anti-stop active
Activating anti-stop mode. This function should always be active
7.5.2 Day
Select the day of the week on which the circulation pump starts in anti-stop mode.
7.5.3 Switch-on time
Setting the pump switch-on time in antistop mode.
7.5.4 Duration
Circulation pump activation time in antistop mode.
7.6 Contact operation mod
The function allows to program the potential-free input as an input of the SG mode or as a
"thermostat".
•
SG mode -
shorting the contact will cause that the controller will start the heating function to
the temperature set in parameter
6.5 Setpoint temperature of the SG function.
•
Thermostat mode
- the heat pump will be switched off when the contact is open. The heat
pump is switched on when the contact is shorted.
Do not connect any voltage signal. This may cause damage to the controller!
7.7 Condenser protection
The condenser is protected by switching on the circulation pump when the outside temperature falls
below 5°C. The circulation pump operates according to the parameters of operating time / break
time. The function should always be active, so while the tank is being heated by another heat source,
standby mode should be activated.
7.7.1 Operation time
Operating time of the circulating pump in the condenser protection function.
7.7.2 Pause time
Breakdown time of the circulating pump in the condenser protection function.
7.8 Min. operation temperature
This function is used to set the minimum ambient temperature (threshold) below which the heat
pump is not operating.
7.9 Min. operation temp. hysteresis
Hysteresis of minimum operating temperature introduces a tolerance for the activation threshold
temperature preventing unwanted oscillations at activation low temperature fluctuations. This is the
difference between the heat pump activation temperature and the temperature of its deactivation
(after the temperature drop).
