Signals for SD systems
The boiler is prepared for control from central operating control (SD system). Operation and failure
signal is presented to terminal block X1 in the boiler.
Operation signal:
indicates switched on boiler (control voltage on). Connects to the boiler terminal
block X1, clamps 3 & 4.
Failure message:
indicates triggered safety thermostat, temperature sensor fault or low control
voltage to the controller. The error that has occurred can be read in the display.
In addition to temperature and power control with 0 - 10 V signal, the boiler is also prepared for
power regulation, ie. the boiler can be controlled so that it has the power that is available at any
given time based on a given subscription limit.
In addition, there are the following outputs:
- Output for indication of set temp. (0-10 V)
- Output for indication of real temp. (0-10 V)
- Output for indication of real time step / power (0-10 V)
