The DELTA 200 controller is designed for automatic switching on and off of the central heating circulation pump or the domestic hot water heater charging pump or the circulation pump, depending on the temperature measured on the sensor. The controller has the following functions:

• temperature programming with the w button
• adjustable hysteresis
• control of the operation of the central heating circulation pump or operation of the pump loading the domestic hot water heater or operation of the circulation pump
• possibility of switching on continuous operation
• COMFORT SYSTEM function, protecting the pump against limescale
• installation protection function against freezing and overheating
• signaling of temperature sensor damage
• possibility of connecting the CONTROL remote control panel with an audible alarm function
• PLUS mode In the PLUS mode, the controller controls the operation of the domestic hot water heater loading pump or the operation of the circulation pump. Switching the pump on and off is done in the opposite way - the pump works when the temperature on the sensor is lower than the set value, and stops working when the temperature rises to the set level.
