Biopel MINI - Installation and Operation Instructions

13. GSM Module *
GSM module allows you to change the basic parameters by SMS messages and receive reports on the
boiler operating status.
13.1 Off
GSM module deactivation.
13.2 On
GSM module activation.
*
Connecting the GSM module to one of the RS data outputs in the control unit.
14. Cascade *
The cascade controller is an additional module that allows control of up to 4 boilers simultaneously
as though it were one. The power of each boiler is then used only when necessary. Boilers are
connected to the cascade controller using RS data cable.
14.1 Operating time
Select one of two control modes, using the CH temperature or the outdoor temperature sensor.
14.1.1 Equithermal
regulation
Switching on of individual boilers based on the outside temperature. Select on the basis of the
outdoor temperature at which the boilers will be switched on. The lower the temperature, the more
boilers activated.
14.1.2 Modulation
Switch individual boilers on the basis of the set CH temperature not being reached within a given
time. Linked to the Boiler Switch-On Temperature and Waiting Time functions.
14.2 Number of boilers
Select the total number of boilers connected to the cascade controller.
14.3 Hysteresis
Hysteresis ensures that the boiler is restarted when the maximum CH temperature has been
reached. When the CH temperature drops by the value set in this function, the boiler is reactivated.
14.4 Low efficiency limit
The lowest temperature level of the boiler. If the temperature does not exceed the set limit in the
interval set in the Waiting Time function, the next boiler is switched on.
14.5 3 Boiler 3 switch-on
temperature
Temperature at which the boiler is switched on.
14.6 2 Boiler 2 switch-on
temperature
Temperature at which the boiler is switched on.
14.7 Boiler 1 switch-on
temperature
Temperature at which the boiler is switched on.
14.8 Waiting time
How long it will take for the next boiler to activate if the specified set temperature is not reached
within the given time.
14.9 Version
Current version of the Cascade Controller.
* Connecting the Cascade controller to one of the RS data outputs in the control unit.
15. Exhaust fan *
Activates the exhaust fan to increase the chimney draft to the prescribed level to prevent smoke
escape.
It connects to the external socket using the RS data cable.
15.1 Fan operating
minimum
Minimum fan speed.
15.1 Fan operating
maximum
Maximum fan speed.
15.3 Version
The current version of the exhaust fan.
* Connecting exhaust fan to one of the RS data outputs in the control unit.
16. Vacuum feeder *
Vacuum feeder transports the pellets over longer distances. From large silos to the boiler
hopper.
16.1 Operating time
Set how long the vacuum feeder will be in operation each day. During this time the pellet
hopper at the boiler should be filled. 30min to 1hr is usually sufficient time to fill the
hopper completely. We recommend to practically verify how long it takes for the hopper
to fill using the Vacuum Feeder and set the exact time to this function.
The control unit will not try to start the vacuum feeder when the hopper is already filled.
This saves the electrical switch on the vacuum container flap.
