The thermostat includes a time clock that is automatically visible in the Home
menu when a programmable schedule is used. If the schedule is not used, the
user has the option to select whether the time is shown in the Home menu.
During a loss of power, the thermostat continues to keep the correct time and
date for at least 4 hours. If the power is off for more than 4 hours, the user will
need to set the time.
The thermostat supports automatic update for daylight savings time. Simply set
Daylight Save to On together with the correct day, month, and year and the time
is automatically updated each spring and fall.
When connected to a tekmarNet
® system, adjustment of the time on one thermostat
updates all connected thermostats. This option can be disabled by selecting the
Local Network Group setting to be On.
