Energy-saving mode
Fig. 7: Temperature sensor - TS2 for energy-saving mode
Cooling units with Multi-Controllers (MC) have an energy-saving mode.
There is a second temperature sensor TS2 (1) for this on the back of the cooling units which measures the switch cabinet
interior temperature.
Functional description:
•
In the delivery condition, the energy-saving mode is activated is no cooling request is received from the controller
for 15 minutes. The control panel then shows "En", see chapter "Controller", Page 16.
•
If the switch cabinet interior temperature measured by temperature sensor TS2 exceeds the set temperature
setpoint, the evaporator fan (inside the switch cabinet air circuit) is switched off.
•
The evaporator fan remains switched on until the switch cabinet interior temperature measured by the
temperature sensor TS2 exceeds the set temperature setpoint+2K hysteresis. The evaporator is then switched
back on and the energy-saving mode is ended.
