Robertshaw RS300N Non-Programmable Thermostat Product Specifications Guide

Robertshaw RS300N Non-Programmable Thermostat

GENERAL DESCRIPTION

The RS300N Premier series of thermostats from Robertshaw are designed for new and replacement commercial or residential applications. The RS300N family has a beautiful new blue backlight and secondary display for the remote sensor bus. The RS300N family thermostats are direct replacements for the Robertshaw 300 series non-programmable products. 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 RS311 N) 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.
