Operating Modes

Normal Operation 

When mains power is initially applied the LCM text display will show the start up message: (including the software 
version and the base model operating range), for a period of three seconds, during which time the controller 
performs a ‘self check’. The LED temperature display will not illuminate during this time. After 3 seconds the text 
will then extinguish and the LED display will show the temperature measured by Probe 1 (T1) - the internal air 
temperature probe. The function LED’s will also illuminate to show which output relays are energised. Therefore, if 
the measured temperature is not within the pre-set temperature range the controller will activate the condensing or 
heating system. All timings (i.e. defrost intervals) will be taken from power up. 

The evaporator coil temperature, measured by Probe 2 (T2) may be temporarily viewed by entering the ‘Supervisor  
Main Menu’ and pressing button1 (Info); (this facility is only available if the evaporator probe is selected by virtue of 
model or as an addition in the parameters). The Condenser Coil and Food Probe temperature may also be viewed 
from this menu if they are fitted by scrolling through the menu using button 1 (    ) and 2 (    ). If no buttons are 
pressed for a period of one (1) minute the ICM display will be extinguished. 

Electrical Isolation 

If mains power is removed from the controller with the unit operational, the entire system will cease and the relay 
outputs will fall low, the LCM and LED displays will be extinguished. When mains power is re-established the 
controller will carry out the initial self-test routine and then the system will re-start and carry on in the ‘Normal 
Operating Mode’. However, if the controller is set to ‘Stand-by’ mode when the mains fails or is removed, on re-
connection the controller will return to the ‘Stand-by’ mode.
