INTRODUCTION
The Remeha Selecta is a wall mounted, fully modulating, condensing boiler, which is
available in two versions:
- Remeha Selecta combi - boiler for central heating and the production of instantane-
ous domestic hot water.
- Remeha Selecta system - boiler for central heating and hot water production via a
calorifier.
The Remeha Selecta series incorporates a pre-mix burner, frost protection, self diag-
nostic servicing LED, and lap-top/PDA connection forsetting and or interrogating the
controller. The boiler can be installed with either a vertical or horizontal concentric (fan
assisted) flue.
The boiler is designed for sealed systems only and is not intended for use with open
vented systems.
The Remeha Selecta combi is equipped with a plate heat exchanger for a rapid hot
water supply. The specially constructed cast aluminium heat exchanger is suitable
for recovery of both tangible and latent heat from the flue gas. The Remeha Selecta
combi can be used as a post-heater for solar heating panels. A continuously monitored
fully pre-mixed burner ensures low NOx and CO emissions. The closed air box means
it can be positioned in almost any space. The appliance is suitable for natural gas or
LPG (only with optional kit, available from Broag).
2.1 Central Heating Control
The central heating output can be controlled by either a standard room thermostat or
alternatively, for higher system efficiency, via the integrated OpenTherm interface. This
option offers full-modulation (100 - 25% of operating load) by using a suitable universal
controller such as the Honeywell Chronotherm Modulating programmable room con-
troller available from Broag. 230 Volt switching controls can also be used in conjunc-
tion with the optional relay kit from Broag.
