SAFETY AND CONTROL SYSTEMS
The heating pump is fitted with the following systems:
Heat pump control based on temperature:
A temperature sensor placed on the exchanger, ensuring the cut of the heat pump when the temperature of the water reaches the required temperature.
The normal cycle restarts when the temperature in the exchanger goes down to a temperature lower of 2°C (factory settings) than this required.
Safety systems include:
The water flow rate sensor installed at the heat exchanger inlet.
The flow rate sensor switches the heat pump ON, when water is flowing through the exchanger and switches the pump OFF in the moment the water
stops flowing or the flow rate drops below its minimum required value.
The sensor of minimum/maximum gas pressure in the cooling circuit.
The temperature sensor at the compressor outlet.
Time delay
The equipment is provided with a time-delay device with the set time lag of Z 1÷3 min. for protecting the control devices in the circuit and removal of
repeated restarts and contactor vibrations. This time delay will restart the equipment automatically within approx. 32 minutes after each interruption
of heat pump operation. The time delay will be enabled even in the case of a short interruption of power supply and prevent the equipment from
starting earlier than the pressures become equal in the cooling circuits. Any interruption of power supply in the course of the delay will not influence
the set time interval.
In the case of failure of any of these systems (a system defect or disconnection takes place or an abnormal temperature is measured), the relevant error
message is displayed on the screen, see chapter 7.3 Error Messages and Their Removal herein below.
Warning: The removal of any of the safety and control systems or putting it out of operation shall cause cancellation of the guarantee.

HEAT PUMP INSTALLATION AND CONNECTION
4.1
SITE SELECTION
The heat pump is intended for outdoor installation and will operate well in almost any outdoor environment, provided that the three following prerequisites
are met:
(a) Do not install the heat pump in a contained area with limited access of air,
where the air cannot circulate freely enough. Both the inflow and outflow
of air should not be restricted in any respect. In the working area around the
heat pump, as indicated in the figure, no items can be placed. Do not place
the pump among bushes and shrubs that can restrict the access of air. Any
obstacle to free circulation will reduce the efficiency of heat exchange and can
even result in stopping the pump.
(b) The equipment shall be installed at a place protected from direct sunlight and
other heat sources, where it can intake air from a naturally sun heated space.
It is further recommended to erect light roofing above the pump to protect it
from direct sunlight and rain.
(c) Do not place the equipment close to any road where it would come into
contact with products of traffic, as any increased dust content in air will cause
progressive deterioration of heat exchange efficiency.
