Heater
- The heater is used to electrically heat the tank. The principle of operation is similar to that in the previous
case but the heater should be connected by means of an additional contactor. The user defines the activation
delta (the difference between the pre-set tank pre-temperature and current tank temperature) below which the
controller activates the heater. Next, the user selects the time period in which the electric heating function will
be active (using
from hour
and
through hour
parameters).
•
Contact (in)compatible with pump
- This setting determines the operation of the voltage-free contact. If the
option
Contact compatible with pump
is selected, the voltage-free contact will always close when the pump
operates (the additional device will be enabled). Otherwise (when the icon is deselected), the contact will open
at each activation of the solar pump.
