The PROTON C.W.U. controller is the latest model of the controller and at the same time the successor to one of the most reliable controllers on the market - the YETI controller. The microprocessor PROTON C.W.U. controller is designed to control the operation of the blower and circulation pump in C.O. installations as well as the C.W.U. pump and has an output for connecting remote control.
The most important functions of the PROTON C.W.U. controller:
- smooth blower speed regulation - NEW ALGORITHM
- the PROTON controller allows setting maximum and minimum blower speeds, which enables precise adjustment of the speed at which the blower will operate
- control of the domestic hot water pump operation
- gradual blower activation from minimum to maximum speeds extends the motor's lifespan and prevents sudden ignition of gases accumulated in the boiler (so-called popping). Competitor controllers have only one parameter responsible for blower power – in the PROTON controller you can set minimum and maximum speeds
Fuel control
This function works by reducing the blower speed to a minimum when the controller detects a temperature drop despite the blower being on. Reducing the blower speed does not cause excessive cooling of the C.O. boiler. This function activates after 30 minutes if the set temperature has been reached, or after 2 hours if the set temperature has not been reached (ignition mode – 2 hours).
"Anti-freeze" function
Below 5°C the controller turns on the circulation pump, which delays freezing of some parts of the C.O. installation (the most vulnerable ones).
"Anti-stop" function
After the heating season, every 14 days the circulation pump is turned on for 1 minute - this prevents the pump from seizing during the summer period - the function works when the controller is turned on.
Automatic setting retention
The controller has automatic setting retention in case of power failure, and returns to the previously performed operation after power is restored.
Return to factory settings
The controller has the option to return to factory settings. This function is useful when the controller is misadjusted by inexperienced operators.
Automatic emergency thermostat
The external thermostat (emergency thermostat) serves as protection for the installation against overheating, which may result from controller failure or improper operation. It is a special element that cuts off power to the blower at a boiler temperature of 90 °C. User-programmable parameters: purge time, pause time between purges, maximum and minimum blower speeds, circulation pump activation temperature, controller shutdown temperature.
Installer-programmable parameters
In addition to the configuration mode available to every user, the PROTON controller has a special mode that allows setting service parameters (additional service manual). The service mode allows programming: blower characteristics – thanks to this parameter our controller can work with any blower available on the market (up to a specified max. power), blower power during purge – you decide at what power the blower should operate during purge, blower speed reduction range – how many degrees before the set temperature the blower speed should decrease, minimum boiler temperature.
Remote control option
A remote control panel or room thermostat can be connected to the PROTON controller. Connecting a remote panel allows the controller to operate in two modes: room and boiler. Connecting a standard room thermostat allows maintaining the set temperature in the room. Thanks to remote control, we can maintain a constant room temperature, which results in fuel savings of up to 30%.
