2.1.2 Condenser sensor
This sensor measures the temperature of the refrigeration system. Excessive condenser temperature is
usually due to poor preventative maintenance, such as poorly cleaned condenser, or condenser fan failure.
The controllers can generate alarms if the refrigeration system temperature rises too high.
Note
Condenser sensor needs to be mounted on the liquid pipe of the condenser.
The temperature is then set as the value of the condenser high temperature
(Ht) parameter. Ensure that the condenser sensor is fixed using a metal pipe
clip (1) or foil tape (2) as shown.
Elstat can supply pipe clips for 6-8 mm and 8-10 mm pipes.

Caution
Do not use cable ties. The head of the sensor is fragile and can be easily damaged. Using
cable ties to secure the sensor head or sensor cable invalidates the warranty.
Do not attach sensor cables to hot pipes or allow the sensor cables to come into contact
with hot pipes.
The value of the high
temperature is set
by measuring the
refrigeration system
temperature, when
the condenser is
approximately 75%
blocked.
