high voltage (HI)

The table below details the high voltage (HI) parameter.
display
Defines the maximum voltage allowed before switching off the compressor.
description
The high voltage (HI) values are approximations and not actual voltage readings (see table below).
1. Must not be used with an external voltage stabiliser
considerations
2. Must only be used with an elstat supplied transformer
3. Only used with ems55advancedand ems55Radvanced

note: Voltage measurement is accurate to ±10%. 265
Caution:
High voltage protection is not calibrated and actual performance can be influenced by several factors.
l
Therefore, total protection cannot be guaranteed.

condenser high temperature (Ht)

The table below details the condenser high temperature (Ht) parameter.
display
Defines the maximum temperature measured in the refrigeration system by
monitoring the condenser sensor.
description
On reaching the condenser high temperature (Ht), the ems controller disables
the compressor and activates an alarm.
