OMNISTAT

1- Display

The Display is used to show current time, temperature, outdoor
temperature (optional), mode, and to give useful information that
will guide you through normal operation of your thermostat.

2- Hold 

Press the Hold key to set the system into Hold  mode.  In Hold
mode, the thermostat will not change its settings by program.  

When hold mode is first turned on, the RC-122 will use stage 2
to get to the new setting as quickly as possible.  Once the
temperature is at or very near the setting, or if the temperature is
already near the setting, the RC-122 will resume energy efficient
operation.
