User Guide

Certiﬁcate of Warranty

The ATW-MINI Heat Pump is designed for heating of family houses or smaller industrial buildings. The product

is to be connected to low-temperature heating systems. This heating system is best suitable for ﬂoor heating,

wall and ceiling heating.

Connection to the classical wall convectors is theoretically possible, but it is limited by the maximum temperature

of the output heating water (50°C, 60°C in High Power systems). At this temperature, the COP (efﬁciency) is lower.

When connecting to the wall convectors, it is necessary to calculate the power at an input water temperature of

45-50°C and to compare it with the thermal loss of the given room.

The heat pump can be used as a source of cooling water.

Basic construction components:

Outdoor Evaporator

This unit is made from a steel plate with high-quality anti-corrosive treatment by electrostatic pulverized

paint. The core of the unit is a two-step DC inverter compressor, which represents an innovation in the ﬁeld of

heat pumps and which guarantees reliability and long lifetime. Other parts include an evaporator with anti-

corrosive treatment and a lifetime of over 30 years, fans with variable rotation speeds, an electronic expansion

valve, controlling and measuring components.

Indoor Unit

The core of the unit is a high-quality refrigerant/water heat exchanger. Other essential part is a high-quality

regulator with sophisticated software which is responsible not only for the operation of the heat pump but

also for the total temperature regulation in the building. The regulator ensures cascade regulation of the heat

pump with backup heater during insufﬁcient power of the heat pump.

It is also possible to connect the appliance to PC through internet interface for comfortable and effective

control of the heat pump.
