Bosch CR50 programmable room thermostat

Comfort is easily achieved with the CR50 controller, which controls the heating system by varying the flow temperature of the coolant. It essentially functions as a boiler remote control. This controller can also control a single heating circuit or a specific zone, but this requires the use of additional MC400 or MZ100 modules and a CW400 controller. This room controller for 1 heating circuit with a temperature sensor automatically configures installed equipment and modulates burner operation.
