I. Description
Temperature regulator ST–707 is designed for CH boilers equipped
with a wormwheel feeder. It controls the water circulation pump , the hot
usable water pump (HUW), the floor heating pump, the circulation pump,
the blow-in (fan) and the fuel feeder. This device may also cooperate
with two three-way or four-way valves, the room regulator ST-208, the
GSM module and the Ethernet module.
The advantage of this controller is its simplicity in operation. The
User makes all changes of parameters by means of the pulse
generator knob.
Another advantage is a large and transparent graphic display, where
the user can exactly see the current condition of the boiler's operation.
