Example:
Part of the heating system is handled by 2 CH boilers and a buffer. The task of the boilers is to heat the water in the buffer.
Gas boiler is connected to voltage-free contact 2 with operation control function. The other boiler is connected to voltage-
free contact 3 with buffer function. Buffer temperature is read by sensor T4 (CH). Additional contact supporting the gas
boiler will be used to control the operation of the other boiler. If the controlled device does not get activated and the
selected sensor fails to reach the pre-set temperature within the delay time, the controller will activate the device
connected to the controlling contact.
8.6. ROOM REGULATOR CONTROL
This algorithm is intended for controlling the device which is to operate according to the signal from the room regulator.
When the pre-set room temperature has not been reached, the contact remains closed (the device is active). Once the
pre-set temperature is reached, the contact opens (the device is disabled).
Additional device operation may be based on signal from more than one room regulator - the device will switch off only
when all room regulators reach their pre-set temperatures. Once DHW option is selected, additional device
activation/deactivation will depend on water tank temperature - when the pre-set value is reached, the device will be
disabled.
