Note 1.
With relays NOT energized, and 'Normally Off' state
selected (refer Note 3)
Heating Relay: NO, closes when heating required.
Cooling Relay: NO, closes when cooling 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.
Single Action Setting is a global setting for the station.
