10.23 Condenser high temperature (Ht)
The table below details the condenser high temperature (Ht) parameter
DISPLAY
DESCRIPTION
Defines the maximum temperature measured in the refrigeration system by monitoring the
condenser sensor.
On reaching the condenser high temperature (Ht), the ems controller disables the
compressor and activates an alarm.
CONSIDERATOINS
1. Is not used with CO2 (R744) coolers.
2. Requires a condenser sensor.
3. To set the condenser high temperature (Ht), measure the refrigeration system
temperature when the condenseris 75% blocked.
4. To disable, set below 50ºC or 122ºF.
RANGE 0.0 to 125ºC (32 to 257ºF)
GLOBAL DEFAULT 0.0ºC (32ºF) - disabled.
10.24 uninterrupted pull down (IPd)
The table below details the uninterrupted pull down (IPd) parameter
DISPLAY
DESCRIPTION
Defines the temperature that if exceeded starts an uninterrupted pull down, i.e. the ems
controller switches on the compressor and runs the compressor continuously until the
product reaches the set point (SP) temperature.
During this time, defrost cycles do not occur.
CONSIDERATOINS
Must be set as follows:
• Above the saving set point (SSP) plus saving differential (Sd) temperature.
• Above the defrost termination (dtd) temperature.
RANGE 0.0 to 30ºC (32 to 86ºF)
GLOBAL DEFAULT 20ºC (68ºF)
