TECH EU-81 ZPID

Principle of operation

ST?81 zPID temperature regulator is intended for charging CH boilers. It controls the water circulation pump, hot usable water pump and the fan. Four optional modes of the pumps' operation: house heating, boiler priority, parallel pumps, summer mode. The controller's casing is adjusted to be assembled in the boiler's installation.

Functions performed by the controller:

Automatic control of the fan
Control of the Central Heating pump
Control of the Domestic Hot Water pump
zPID software

Equipment of controller:

LCD display
CH temperature sensor
DHW temperature sensor
Flue gas temperature sensor
Temperature protection (thermal overload rely)
Panel casing for installation of the boiler, made of high quality materials resistant to high and low temperatures
The possibility of installation on the boiler in OM-01 casing
