5 DESCRIPTION OF THE APPLIANCE
5.1 Characteristics
The
Sime SOLO HE EV
cast iron and condensing thermal units are integrated systems with diesel Low NOx blown-air burner. They are
also equipped with a heat recovery device, flue gas side, which classifies them as “condensing”. They are specially designed for users
who privilege high performances, silent operation and compact dimensions.
– The
SOLO HE EV
thermal unit is the version for space heating only. It can be a TYPE B23P (open), if it draws combustion air from the
environment in which it is installed, or TYPE C23P (sealed), if it draws combustion air from the outside. When the thermal unit draws
combustion air from the room in which it is installed, this room MUST be equipped with adequate aeration vents sized according to
the laws in force in the country of use.
– The burner combustion is optimally balanced and guarantees high performances, resulting is considerably lower running costs.
5.2 Operation
Prior to starting up the thermal unit, we suggest setting the
heating thermostat (4) to roughly 3/4 of the adjustment range
(roughly 75°C) and then activating the general and main switch-
es (8) to power the system electrically. The green signalling LED
(3) will light up to signal that the system is powered.
When a heat request arrives, with the thermostat in request
mode, the fuel will start heating for a few minutes with the
burner stationary. The following operations occur in sequence:
powering of the burner and of the ignition transformer; ignition
of the flame and starting up of the system pump.
The flame will remain on until the temperature set through the
heating thermostat (4) of the control panel has been reached,
while the system pump continues to operate in order to use the
heat generated (available). The burner will then switch on and
off in an alternating manner until the temperature requested by
the room thermostat is reached.
The temperature of the water contained in the cast iron body will
appear on the thermometer (2).
