Installing Or Changing The Batteries; Display Map - Robertshaw RS4110 User Manual

Installing or Changing the Batteries

To remove the battery compartment gently
squeeze the ribbed edges on both sides.
The battery compartment will pull down from the
thermostat body and will detach. Install two AA
batteries following the polarity as shown inside
the compartment. Place the compartment back
into the thermostat.
When the batteries are low the thermostat will enter a low battery mode.
Low battery mode has two levels.
• LEVEL 1: The low battery icon will be displayed.
The thermostat will continue to operate. Replace
the batteries as soon as possible
• LEVEL 2: The low battery icon will flash. If 24V AC
is present the thermostat will continue to operate
if the batteries are discharged or removed. If 24V
AC is not present the thermostat runs on
batteries only and THE SYSTEM WILL NOT OPERATE.
Replace batteries immediately.
The clock will continue to run for 10 minutes when the batteries are
removed.
Replace batteries if leaving thermostat unattended for more than 30 days.
