General Introduction - Airwell AW-WHPMA04-H91 Manual De Instalación

2 GENERAL INTRODUCTION

These units are used for both heating and cooling applications and domestic hot water tanks.They can be combined with fan
coil units, floor heating applications, low temperature high efficiency radiators, domestic hot water tanks and solar kits, which
are all field supplied.
A wired controller is supplied with the unit .
If you choose the built-in backup heater unit, the backup heater can increase the heating capacity during cold outdoor
temperature. The backup heater also serves as a backup in case of malfunctioning and for frozen protection of the outside
water piping during winter time.

③ Additional heating capacity provided by backup heater.
Domestic hot water tank (field supply)
A domestic hot water tank(with or without booster
heater) can be connected to the unit.
The requirement of the tank is different for different
unit and material of heat exchanger.

The unit have a freeze prevention function that uses
the heat pump or backup heater to keep the water
system safe from freezing in all conditions. Since a
power failure may happen when the unit is unattended,
It's suggested to use anti-freezing flow switch in the
water system. (Refer to 9.4"Water piping").
