Description
The
ST-45
temperature regulator is intended for use with central heating
boilers. It is used to control the water circulation pump, hot consumption
water pump, floor heating pump, mixing pump, blow (fan) and fuel
feeder. The ST-45 regulator features two modules: graphic display panel
and control panel.
The ST-45 can be used with two optional additional three-way or
four-way valve control modules. The regulator has been designed
and made for comfort.
It is very easy in use. All parameters are adjusted with a convenient
knob
(encoder). The ST-45 regulator features also a graphic display that
shows the current status of the boiler.
If the furnace temperature is lower than the
setpoint temperature
, the
regulator is operated in its
duty
cycle, i.e. the blow is active and the
operation time of the fuel feeder is set by the user (both operation and
stand-by times are set).
