Control System
Reaction: Heating Unit
Circulation pump and heating element are off.
Control lamp at heating element is off.
Circulation pump runs.
Heating element is ready for operation.
-> Heating unit starts to heat, when the return water flow
temperature falls below the adjusted temperature.
Heating unit warms up the water until the adjusted water
temperature value is reached at the thermostat (a
desired temperature of return water flow is adjusted at the
thermostat, mounted on the return flow pipe).
Control lamp at heating element illuminates.
After having reached the desired temperature, heating
element switches off --> Control lamp at heating element
stops to illuminate. If return flow water temperature is lower
than the adjusted value, the heating element will be
automatically switched on again...
Control lamp at heating element switches off. Security
temperature limiter (STB) triggers. Heating element stops to
heat. After cooling down phase -> it is necessary to switch
on STB manually!
See description for STB activation, page 24 .
