2. Overview
The run/standby panel is used to automatically change over three Air Conditioning indoor units.
The panel will be fed with a 240VAC power supply.
The panel is fitted with a day time controller switch with battery back-up and latching relay to permit two indoor units to
run for instance 7 days, after this the panel will automatically change over to the next indoor unit for 7 days etc.
The panel is designed that if one indoor unit goes to fault while running it would automatically bring in the backup
indoor unit.
The high temperature thermostat option will allow the three indoor units to run together if a high temperature exists. A
high temperature warning lamp will indicate.
The sounder & mute option will allow any fault condition received by the control panel (i.e. unit fault, or high
temperature) to initiate a sounder on the panel door. A mute button is fitted to silence the sounder.
Volt free terminals are fitted to allow fault signals to be transmitted to any external monitoring system.
The panel is supplied with accessories to interface with the Air Conditioning indoor unit:
- 3 wire adaptor to control the On/Off
- PAC-SF40RM to monitor Run and Faults with Mr Slim indoor units
