Robertshaw Deluxe Programmable Thermostats Thermostat User Manual


 
Changing INSTALLER SETTINGS
The INSTALLER SETTINGS are selected based on the type of equipment you have in your facility. This feature should be set only by
a certified HVAC technician. Changing these settings could result in higher energy costs and may even damage the equipment. You
should only change the FILTER MONITOR length should you get a new type of filter.
Energy Efficient Recovery™ (EER™)
Energy Efficient Recovery™ is an energy saving feature. During a set back period (or set up in cooling), it allows the thermostat to
look up to two hours ahead to determine when to turn on the heating (cooling) system. During this time period, the second stage is
locked out to allow the first (and most efficient stage) to bring your facility to the desired temperature.
Indoor Sensor
The remote indoor sensor (part #9020i) can be used to improve the comfort of your home. When used in conjunction with the local
sensor on the thermostat, the two sensors average the sensed temperature and control to that average temperature.
You also can use the remote sensor in a stand-alone situation when you want to control the temperature in a remote area but have the
thermostat in a secure location.
Outdoor Sensor
The remote outdoor sensor (part #9025i) can be used to aid in the comfort of your facility or simply as a sensing device to inquire
about outdoor conditions. In most applications, the thermostat will have a display of the temperature sensed by the remote outdoor
sensor. With a heat pump system, the remote outdoor sensor can help determine when to turn on the second stage of heating for opti-
mal comfort. The remote outdoor sensor should be installed on the northern wall of the facility, away from direct sunlight or other heat
sources that may affect its sensitivity.
