Description of the device
The Multifun control system regulator is a modern multiprocessor control system for heating
devices. The basic version of the system consists of a control panel and a main run-time
module. These devices are connected via a LAN cable and an RJ45 type connector. Additional
modules can also be connected using this cable. Data transfer is carried out in RS485
standard. A modified MODBUS protocol ensures a correct data exchange
.
The main run-time module
For the basic operation of the device, boiler sensors need to be connected to the run-
time module without which the boiler will not work properly:
• Boiler feed temperature sensor [BOILER FEED]
• Feeder temperature sensor [FEEDER]
• Flame sensor [PHOTODETECTOR]
To successfully run other functions of the controller, appropriate sensors must be connected
to the run-time module:
• Fan hall generator* - recommended when using a fan with a revolution number sensor.
• Hot water temperature sensor [HW] - when water heating.
• Central Heating temperature sensor [CH] - to control the mixing valve
• Return temperature sensor of the heating medium [Boiler Return] - protection against cold
water returning to the boiler. The sensor is necessary to work with the mixing valve or the
circulating pump
• External temperature sensor [External] - required if the weather function is active
• Room 1 temperature sensor [Room1] -
