Application
The controller is designed for cascade control of heating, air conditioning and other installations built with more than one unit.
Method of working
In heating or cooling mode, the controller monitors the measured and set
temperature and, according to the set parameters, turns on or off a certain
number of units to maintain the set temperature.
For a uniform load, it is planned to change the order of turning on and off
the stages according to “FIFO” logic.
Control outputs:
The regulation zone “Zone_reg” is immediately before the temperature setpoint
in the equalizer or buffer vessel “T_set”. When the measured water temperature
is less than the temperature defined by the regulation zone “Zone_reg”, all
available stages are switched on and all installed power is supplied.
Upon reaching the regulation zone, a part of the steps will start to be turned
off, with the supplied power being proportional to the temperature difference
between the set and measured temperature in the equalizer or buffer vessel
(T_set – T). When the measured water temperature is greater than the set
point, all stages are off and we have no power output.
When the contact from the safety thermostat input is opened, all outputs are immediately switched off.

Programming
Make sure the controller is not in the off state, otherwise there will be an
OFF message:
Attention! The controller can be turned on and off from the front panel
or remote control input. The controller turns off regardless of where the STOP
command is given, but can only be turned on when there is a START command in
both places.

- Remote control input – START when the contact is closed between terminals 42 and 43, STOP when the contact is open. When not in use a bridge must be placed between terminals 42 and 43.
- Protective thermostat input – when the contact is open, it triggers the protection. When not in use, a bridge must be placed between terminals 40 and 41.
Recommendations for the installation of the elements:
- Tbufer temperature sensor, installed in the equalizer or buffer vessel.
- room temperature sensor, installed in the room in a place protected from direct sunlight and internal heat sources (household electrical appliances, audio-video equipment, etc.).
