DRY CONTACT LATCH SCHEME - If Latch OFF is selected,
the thermostat runs normally. If Latch ON is selected, the
thermostat will ‘wait’ in unoccupied settings. A
momentary closure of the dry contact will put the thermostat
into the appropriate period, (Morning, Day or Evening)
for 30 minutes.
If the contact closure occurs during Night then the
thermostat will remain in Night settings until the Morning
period. Then it will return to unoccupied. This is used in
a hotel room with a motion detector to allow for comfort
settings during sleep periods without movement.
