Page 3: Description
DESCRIPTION The RC-100 is a precision digital thermostat specifically designed for heat pumps. It has the capability of being controlled both locally and by remote control. It offers programmability, stand alone operation, and robust, optically isolated communications with automation systems, utility control systems, and personal computers. -
Page 4: Location
LOCATION When replacing an existing thermostat, install the RC-100 in the same location. If the existing location doesn't meet the following criteria, choose a new location to mount the RC-100. When choosing a location for the thermostat: 1. Ensure that the thermostat is mounted about 5 feet above the floor and is at least 2 feet from an outdoor wall. -
Page 5: Mounting
MOUNTING When mounting the RC-100, grasp the thermostat by the sides, avoiding the keys, and unsnap the base from the face. Holding the base to the wall so that the word "TOP" is upright and facing you: 1. Mark the two mounting holes on the wall using a pencil. - Page 6 Connect each wire to the terminal strip on the thermostat base per the wiring diagram for your system application - See Figures 4 - 5. Form the thermostat wiring so that the cable lies flat between the terminal strip and the center of the thermostat base - See Figure 2. Figure 2 - Forming thermostat wiring If a remote system is being used with the thermostat, connect the...

(usually accessories to a heat pump), are not used. The RC-100 automatically controls auxiliary heat efficiently. The RC-100 requires at least 1 stage of auxiliary heat enabled at all times. If the heat pump is equipped with an outdoor... -
Page 11: Power Up
POWER UP 1. Double check wiring, be sure that there are no stray wires or wire strands at the connections. 2. It is not necessary to connect the remote system (COMM) cable at this time. 3. Connect power to the control transformer and system. The display will show all segments for about 5 seconds. -
Page 12: Installer Setup
INSTALLER SETUP This section describes the items that the installer must setup as part of the thermostat installation. The Installer Setup mode is used to configure the general operating parameters of the thermostat. When in Installer Setup mode: 1. The small digits on the top of the display are the item number. 2. -
Page 13: Address
The word "default" indicates the initial setting when the thermostat is delivered from the factory. 00 Address If you are using Communications Mode 0 or 1, and you are installing more than one thermostat, each must be set to a consecutive address, starting at 1. - Page 14 * Energy Efficient Control (EEC) of Auxiliary Heat: Select 0, 1, 4, 5 to enable EEC, or 8, 9, 12, 13 to disable EEC display. See Owner's Manual for description of EEC. The default setting is 1.
-
Page 15: Display Options
In most heat pump installations, the auxiliary heat is electric resistance heat and the Energy Efficient Control (EEC) should be turned on (settings 0, 1, 4, 5). If the heat pump is equipped with a more efficient auxiliary heat, such as hot water supplied by a gas water heater, you may want to turn EEC off (settings 8, 9, 12, 13). -
Page 16: Cool Setpoint Limit
05 Cool setpoint limit This item is used to limit the temperature setting in cool mode. The desired cool setting can never be set below this setting. The default setting is 51. 06 Heat setpoint limit This item is used to limit the temperature setting in heat mode. The desired heat setting can never be set above this setting. -
Page 17: Heating Minimum On/Off Time
(1 = - 29 to 59 = + 29 - Seconds per day - 30 = No change) The default setting is 30. Note: If an HAI automation system is being used, the controller system time is sent to the thermostat every minute. This adjustment will have no effect. -
