COMPUTHERM
WPR-200
Pump controller for solid fuel
and multi-fuel boilers
The COMPUTHERM WPR-200 is a pump controller developed for solid fuel and multi-fuel boilers. It enables the control of pumps (heating circulation pump and domestic hot water pump), thereby increasing operational safety and comfort. The task of the pump controller is to switch the pumps on and off depending on the measured and set temperatures, ensuring that they operate only when necessary. Intermittent operation results in significant energy savings, increases the lifetime of the pumps and reduces operating costs. Its large digital display allows easy and accurate temperature measurement and adjustment, and facilitates the modification of operating modes and settings
Important functions:
- It turns on/off the pumps connected to it based on the set and measured temperature.
- It controls the DHW (Domestic Hot Water) and heating circulation pumps in parallel.
- The cables required for commissioning are pre-installed factory accessories.
- With its digital display, you can easily check the settings and the measured temperatures.ű
- In addition to temperature-based control, it can also be used in manual mode.
- The switching sensitivity can be adjusted as required.
- It also provides the option for summer (DHW only) and heating modes.
- Option for Domestic Hot Water (DHW) heating priority.
- It has an activateable pump protection function that prevents the pump from sticking.
- It has a frost protection function that can be activated, which prevents damage to the pump in case of light frost.
- It has an overheat protection function that can be activated, which automatically turns on both pumps (with acoustic and visual alarms) to assist with heat dissipation from the boiler.
