5. Connect the HE KIT fan power cord.
6. Connect the room temperature sensor.
7. Plug in the power cord into 220/230v A.C. 50 Hz . The emitter
is provided with an open cable gland so that the cable can be
removed and be plugged into an outlet socket that is inside the
cover (check current regulations).

HE SYSTEM OPERATION

11.1

GENERAL DESCRIPTION

The HE system turns the VARESE emitter into a highly
efficient apparatus by forcing air flow through the
heat exchanger by using ultra silent brushless fans,
electronically modulated by a processor connected to a
room temperature sensor and another reading the water
tem-perature of continuously entering water.

OPERATION

This system is designed to operate completely
autonomously and unattended from the first connection.
Through the water inlet sensor, the system starts and
stops automatically when the boiler or heat group is
started or stopped.
In addition, it uses all the heat stored in the emitter core
even though the boiler or thermal unit has stopped. When
the system detects that all the useful heat has been
extracted, it will stop automatically.
2 touch-sensitive buttons that sound when pressed:
1. Mode: alternative between modes. Each icon is backlit by LED
when active. Tap this button to change the active mode emission.
2. Stand-by: Force HE system shutdown. The red bar in the middle
is backlit in red and blinks or unchanging to report a stand-by
forced by the user or stand-by because of low temperature in
the water inlet.
11.2 MODES
Auto mode: with the room sensor, the system
automatically modulates the emission capacity of the
system. The word AUTO is backlit in blue in this mode.
Speed fan
Eco Mode: Economic mode with lower emissions and almost
negligible noise level. ECO icon back lit in green.
Comfort mode: average emission mode, suitable for normal
boiler ignition: COMFORT icon back lit in red.
Boost mode: high performance mode. The emitter is at its
maximum capacity issue. Recommended for situations of
extreme cold or ignition after long periods of absence from
the home. "Boost" icon backlit in red.
