The EU–48 temperature regulator is designed for central heating boilers. It controls the water
circulation pump ., the hot utility water (C.W.U.) pump, the floor heating pump, the circulation pump,
the blow (fan) and the fuel feeder. Two modules controlling three-way or four-way valves can be added
to the EU–48 thermoregulator (this is an additional option).
The advantage of this controller is its simplicity in operation. The user makes all changes of pa-
rameters with the knob of the pulse generator. Another advantage is a large and clear graphic display,
where the user can exactly see the current condition of the boiler's operation.
Any comments concerning the program should be reported to the boiler's manufacturer.
Each controller should be set individually for own needs, depending on the type of fuel used for
burning as well as the type of the boiler. The TECH company does not bear any responsibility for improper
controller settings.

navigating the menu which takes place by means of the pulse generator (knob). The boiler's opera-
