Electronic boiler microcontroller C.O TECH ST-28 is the appropriate heating controller for solid fuel hand fired boiler. It supports two up to two pumps (central heating water circulation pump and domestic hot water pump) and a blower fan.

Boiler controller allows manual operation and control of each plugged in device. Optional an extra room temperature controller can be connected to the steering by a two-wire cable.

In room thermostat heating mode, the boiler room controller works to achieve the set-point room temperature. Room thermostat control is available as an optional accessory. The boiler controller has security software features protecting the installation and the boiler from overheating in the form of automatic disabling of boiler ventilator and switch on pumps to get rid of excess heat.
