Smooth Setback Recovery (via DIP switch #6)
Smooth Setback Recovery (SSR) affects the way the
thermostat responds to program events. If SSR is disabled,
the thermostat will react to a program event at the time the
event occurs. However, if SSR is enabled, the thermostat
will react to a program event before the event occurs such
that the desired temperature is reached at the time of the
event, not after.
Fan Control
AUTO or ON modes.
I/O Relays
All thermostat relays are latching type to minimize power
consumption.
