Operation of a single heat generator
Settings:
1/2/11/Mod = m (Modulation)
1/2/11/Mod = 1 (switching heat generator)
BUS-ID = -1 (single HS with desired temperature
presetting)
Settings on the Manager/Cascade controller:
HS1 Type = Single stage HS switching!
HS1 BUS = CAN BUS
Stand alone
The heat generator is activated once the temperature
drops below the set temperature.
Deactivation occurs at T-Des + 5K.
Modulation: The mixer relays regulate the desired
temperature of the heat generator by adjusting the air
damper.
Single HS with Manager via CAN BUS
The burner is switched according to Manager presettings
Modulation: The mixer relays regulate the temperature at
Sensor T-BOILER to the value
T-BOILER DES preset in the Manager.
Modulation via air damper
The initial damper adjustment occurs with a delay of
approx. 3 minutes after a burner start. While "Burner OFF"
and during the first three minutes after "Burner ON", the air
damper is constantly driven towards in "CLOSE" direction.
Connection
During this operating condition, the relays T3 T4 is
switched in parallel with the HS pump => When the HS
provides the potential (L1´) for the air damper relays, it is
connected to the terminal L1´ on the controller. The HS
pump is then connected to T3 (= pump phase and bridge
T4 to power supply phase L1). The air damper for
modulation is connected to the contacts 5 (OPEN), 6
(CLOSE) and 8 (potential).
