3 INTRODUCTION
3.1 DESIGN & OPERATION
The Gabarron MATTIRA COMBI boilers are electrically
heated combi boilers providing wet central heating through
a standard radiator system (or underfloor system with
special kit) and domestic hot water (DHW) delivered from
an integral unvented store at mains water pressure.
Outputs are from 2 to 15kW. Maximum output can be
adjusted to match the heat requirement of the system or
the limitations of the incoming available power supply.
Operation is possible on three phase N or single
phase 230V - 50Hz.
The boilers are designed for internal installation on a
suitable wall with consideration for the total weight of the
appliance when full.
A digital control panel provides user control to adjust the
temperatures of heating and hot water. A power
modulation feature automatically adjusts the heating output
to the demand to ensure economic operation.
A suitable external time clock/room thermostat
should be fitted (not supplied).
An adjustable thermostatic blending valve
should be fitted on the hot water supply to
ensure a safe and economic supply of hot water
(not supplied).
