INTRODUCTION
Thank you for purchasing your new RC-90 electronic communicating
thermostat. Your thermostat will provide you with comfort,

DESCRIPTION
The RC-90 is a precision digital thermostat for single stage heating
and cooling systems. It has the capability of being controlled both
locally and by remote control. It offers programmability, stand-alone
operation, and robust communications with automation systems,
utility control systems, and personal computers.
There are several items that can be configured at the time of
installation. These items have a check box () for your installer to
indicate which features are used in your system.
The RC-90 can act as the Master thermostat in a zoned heating
and cooling system. Setting the Master thermostat to HEAT mode
will allow it and the other zones to heat. Setting the Master to COOL
will allow it and the other zones to cool. Setting the Master to OFF
will turn off all other zones.
MAINTENANCE
Your new thermostat is maintenance free. There is no battery to
install or replace. If necessary, clean unit carefully with a mild soap
solution on a soft cloth.
