Note 1.
With relays NOT energized, and 'Normally Off' state selected (refer Note 3)
NO = Normally Open.
Heating Relay: NO, closes when heating required.
Note 2.
All relays are change-over.
Note 3.
Each relay can be configured for a 'Normally ON' or 'Normally OFF' output state. (E.g. for fail safe operation.)
The 'Normally ON/OFF' settings are retained in software on power down, but the relays are de-energized.
The 'Normally ON/OFF' state of the relay can be changed in the Advanced dialog box for the onboard relays,
or using the Relay States dialog box for the 2100-R2. Refer to MicroScan Configuration Manual.
Note 4.
LED indication on each output when each relay is energized.
Note 5.
In Dual Action mode, if the controller is set to heat only, the cool relay is always off. If the controller is set to
cool only, the heat relay is always off. Likewise when using Manual Mode in the heat only mode, only the state
of the heat relay can be changed, and on the cool only mode, only the state of the cool relay can be changed.
Note 6.
Dual Action Setting is a global setting for the station.
