Rooftop Commercial AC Controller Functions Temp. sensor inside Network address inside To get the accurate temperature information of the project site, the FCUKZ control box is integrated with the temp. sensor of room temperature T1 and the evaporator intermediate temp. sensor T2. The FCUKZ control box is integrated with the MD-NIM01 to achieve a network address. With the network address, the FCU can be controlled by the centralized controller MD-CCM03 or the PC monitoring system. RC receiving The FCUKZ control box has a infrared receiving panel, which helps receiving the signals from the wireless controller. Access to network monitoring With the FCU control box the fan coil unit can be connected to the centralized controller MD-CCM03, which bridge the fan coil unit to the network monitoring system.

KJR-25B offers various kinds of reminding to keep the ventilating system working efficiently Your thermostat is set at the factory to cycle at 2°F span=1 span=2 span=3 and safely. The controller will not only remind (1°C) above and below the set temperature. The span equates 2.

The thermostat counts the hours your system’s filter has been in use. To maximize the system’s performance and energy efficiency, the filter should be clean or change regularly. When the total system running time for heating and cooling reaches 400 hours, the filter indicator normally for the sake of low battery. 7°C 35°C 45°F 96°F Compressor protection flashes as a reminder.
