IGNITION
If the water pump #1 is used solely for heating domestic water,
only On/Off features are needed. Heater maintains a steady
temperature of 70 C°/158 F° in the hot water boiler
automatically. When the water pump #1 is used also for radiator
heating, a target room temperature can be set in the thermostat.
Room temperature is measured with a wireless sensor, which is
placed in the desired location.

UNIT FORMS PRESSURE
40 EA heats water with heat transfer fluid
circulation. Fluid must be either
Water pumps form pressure, which circulates
the fluid inside the unit and in heating pipes. It
is very important to not let the unit reach
excessive pressure. Therefore, an open
expansion tank must be used at all times.
Also, a 1.5 Bar overpressure valve should be
installed in the system.
IMPORTANT TO NOTE
Pause Mode automatically turns the burner off if the
water temperature rises above 82 C°/ 180 F°. The
unit will start heating again when the water
temperature drops to 55 C°/130 F°. It will attempt to
maintain a steady 70 C°/158 F° degrees.
PAUSE MODE
If the heater is in Pause Mode,
Paused and a Pause Icon will appear
on the screen.
Heater will re-start heating again

Water pump #2 is intended for floor heating and
therefore operates with more powerful flow, sufficient to
provide heat transfer fluid circulation in the heating pipes
underneath the flooring.
