1. OPERATING/USER INSTRUCTIONS
1.1 Introduction
Dear Customer,
Thank you for having chosen the
Tempra 12/18
, an advanced-concept FERROLI wall-hung boiler
featuring cutting-edge technology, high reliability and constructional quality. Please carefully read
this manual and leave it with the end user.
The
Tempra 12/18
is a
high efficiency
heat generator for central heating systems, operating
on natural gas or LPG.
The boiler can be connected to an external hot water cylinder for the production of domestic
hot water.
The boiler body is made up of a
copper heat exchanger
, the special shape of which guarantees
high heat exchange efficiency in all operating conditions, and
an atmospheric
burner
featuring
electronic ignition with ionisation flame control.
The boiler is completely
sealed
from the surrounding environment: the air required for combustion
is taken in from the outside, and a fan is used to expel the flue gases. The accessories supplied with
the boiler also include a variable-speed pump, expansion vessel, safety valve, air pressure switch,
temperature sensors and safety thermostat.
The
microprocessor-based
control system means that the operation of the appliance is almost completely
automatic. The central heating output is automatically regulated by the control system according to
requirements. The domestic hot water output (with external hot water cylinder installed) is automatically
and continuously controlled to ensure both comfort and economical operation.
The user simply has to set the temperature required inside the home (using the optional, yet
recommended room thermostat) or set the system temperature and the required domestic hot
water outlet temperature at the cylinder stat. The regulation and control system will then ensure
optimum operation all year round.
