Overview

It's Back! The RS300 Slimline® Premier family thermostats are direct replacements for the Robertshaw Slimline® 300 series programmable and non-programmable thermostats, with powerful new features!

The RS300 family has a beautiful new blue backlight and secondary display for the remote sensor bus.  Now with universal operation, they can be configured to control conventional HVAC equipment or heat pump equipment with both traditional and dual fuel heat pumps.  The pushbuttons on the thermostat can be locked to give restricted override capabilities, and the optional Occupancy Sensor enables automatic energy savings.  The advanced remote sensor bus (except RS311N) allows up to 6 indoor remote sensors, an outdoor sensor, and up to 3 auxiliary sensors for needs such as supply air, return air, water temperature, walk-in freezers and refrigerators, and any other temperature monitoring desired.

Economizer control is included in one programmable and one non-programmable model.

There are four (4) RS300N non-programmable models with the traditional Day/Night dual setpoint configurations, and the two (2)  RS300P models are 5-1-1 day, 7-day programmable, and can even be set up as non-programmables.
