FAQ

Client:

What does words mean: CH and WUW

JUMAR:

CH - Central Heating, WUW - Warm Usage Water

Client:

Why should I use additional pump for warm usage water ??

JUMAR:

Our controllers have two outputs for pump:  for central heating and for warm usage water pumps. This control enables heating of the usage water tank to the temperature specified by the user and prevents cooling of the tank, e.g. in the event of a sudden drop in temperature caused by the boiler burning off. 

Client:

Can the boiler temperature rise uncontrolled during controller failure ??

JUMAR:

The controllers have additional inputs for connecting the STB fuse (thermal fuse). Incrising the temperature above safety temperature cuts off the heating source: fan and feeder.

Client:

Why does the airfan diode blink when the air fan is running ?? 

JUMAR:

The regulators have speed regulation of the air fan for better boiler combustion. The LED blinking is more frequent at higher speeds. At maximum speed the diode is constantly on.

Client:
