CHAPTER 8
HIGH PRESSURE SWITCH (HP)
TAEevo Tech MINI 05÷10 models are furnished with a high pressure switch (HP), not present in TAEevo
Tech MINI 02-03 models.
It monitors the discharge pressure of the refrigerant compressor and prevents it from increasing to dangerous
levels for the compressor and people within the immediate vicinity.
It is of “manual reset” type. It opens the power circuit of the compressor and of the fan (see wiring diagram).
When the discharge pressure of the refrigerant compressor decreases and falls below the reset point, it
resets. Therefore it is necessary to manually restart it to start the unit (press the reset button on the top part
of the cover B).
The setting values are fixed.
In the event of replacement, the pressure switch is screwed to a SCHRAEDER valve which prevents the
refrigerant from leaking.
The TRIP and RESET values of the pressure switch are indicated in the following table:
