V.f.2)
Firing up the PLT Boiler (pellet)
This option is used to adjust the voltage-free signal to fire up the pellet boiler. The user sets the
Activation Delta, namely the difference between the tank's set temperature and the tank's current
temperature which leads to the controller sending a signal to fire up the boiler. Then, the user selects
the time interval in which this function will be active (using the function "From" and "To")
V.f.3)
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 sets
the activation delta (the difference between the tank's set temperature and the tank's current
temperature), below which the controller will activate the heater. Then, the user selects the time interval
in which the electric heating function will be active (by means of the "From" and "To" functions).
V.f.4)
Contact (not) Consistent with Pump
This setting determines the operation of the voltage-free contact. If the icon "Contact Consistent with
Pump" is marked, then the voltage-free contact will close always when the pump operates (the
additional device will activate). Otherwise (when the icon is unmarked), the contact will open at each
activation of the solar pump.
V.g)
Calculation of Energy
Entering the following values correctly will make it possible for measure the gained energy in a more
precise manner.
V.g.1)
Flow
At this point, the user should specify the quantity of glycol that flows through the pump in one minute.
V.g.2)
Type of Agent
This function allows the user to identify the agent used: ethylene glycol, propylene glycol or water.
V.g.3)
Glycol Solution
At this point, the user should specify the percentage concentration of glycol in water.
