Energy saving operation
: Energy saving operation is run when all the following conditions are met.
1) One or more ERV units must be connected to MWR-WE10 (without or with indoor unit(s) )
2) Either the indoor unit or ERV must be ON (if the indoor unit is ON, it must not be FAN mode).
3) ERV must not be in Outing mode
4) ERV external control must not be enabled.
5) ERV must not be in “Centralized” control mode.
6) ERV must not be in “Kitchen Hood” control mode.
NOTE : The sub wired remote controller does not support energy saving mode

3. Damper stop in detection of two short interval pulses
1. Internal damper operation start
2. Pulse from switch detected by controller.
3. Damper stop in detection of one long interval pulse
• Damper error - After the damper starts operating, E654 is displayed when the pulse from the switch is not
detected for 100 seconds.

- Two minutes after power-on, the CO2 sensor is maintained
at 500RPM as preheating standby
- An error is detected when the pulse from the CO2 sensor is
not generated for 2 minutes.
