1.1. General information

Congratulations on your purchase of heat pump Hotjet. Get familiar with these instructions to get the best

use and a long service from the pump.

The heat pump is a compact unit designed for heating water for hot service water and for heating.

The source of heat is the external air, of which heat is transferred to water in an exchanger. The heat pump

is a long service life and a very safe product.

We wish you a trouble-free operation and a lot of thermal comfort..

1.1.1.System description

The Hotjet heat pumps are compact units designed for outdoor and indoor installation. The series Hotjet i

units are intended for indoor installation in an object, and the series Hotjet e units are an alternative for

external installation out of the object. These models take the energy from the air, and that is why it is not

necessary to bore holes or to install ground collectors.

The series Hotjet w are intended for the ground-water or water-water systems. The heat source is a

borehole, a ground collector or a technological or waste heat.

The heat pump is equipped with the Siemens RVS41 or RVS61 regulators. The regulators controls the

running of the actual heat pump, heating of the hot service water, charging of the storage reservoir,

controlling the three-stage bivalent source, directional and heating radiators circuits, swimming pool water

heating and many other parts of the heating and cooling system.

The regulators algorithms are practically identical, and differ only by the number of inputs, therefore the

number of simultaneously connected and regulated subsystems. Each series RSV regulator is extensible by

3 input and 3 output module.

Up to two AVS75 modules can be connected to one RVS.

It is possible to interconnect up to 16 heat pumps of various models and outputs into the so called cascade

and in this way increase the total output capacity of the installation. At the same time, the stage regulation

becomes also available.
