Introduction The UL listed Phone-A-Stat (model # 7632 ) is designed and approved for the safe operation of remotely controlling four independent loads, such as a sprinkler system or a water heater via your telephone or manually on-site. Another example would be to connect an output to the thermostat s phone interface (which requires a dry contact) to switch from Comfort mode to Vacation mode and vice versa. This would allow you to turn your heat up or down via your telephone or manually on-site. Safety Guidelines 1. DO NOT USE WITH FLAMMABLE OR EXPLOSIVE FLUIDS SUCH AS GASOLINE, FUEL OIL, KERO- SENE, ETC. 2. DISPLAY PANEL MUST BE MOUNTED INDOORS. FOR OUTDOOR APPLICATIONS CONSULT FACTORY. 3. TO AVOID ELECTRICAL SHOCKS, THE DIRECT CONNECTION OF A LOAD EXCEEDING 30 VAC IS NOT PERMITTED UNLESS THE PHONE-A-STAT IS INSTALLED INSIDE A CERTIFIED ELECTRICAL BOX. Tools & Supplies needed for installation 1. Flat blade screw driver 2. Small phillips screw driver 3. Drill and 9/64 drill bit to make a pilot hole for the mounting anchors 4.

2. Other Information #10. Remote Unoccupied. 3. When the REM input is connected to a central system or a telephone controller and a signal is received through this input, the Phone-A-Stat will switch to the unoccupied set point. The yellow LED on top of the display turns on when (Emergency Heat control mode is selected and the Aux. heat is on) The icon is displayed. For details on how to operate your Phone-A- Stat, refer to pages 1-6 of this manual. When this mode is activated remotely it can only be deactivated remotely. Although, it can be bypassed for a 2-hour period (see 10a.). #10a. 2-hour Temporary Bypass When the Phone-A-Stat is in Automatic or Remote Unoccupied mode, you can temporarily bypass the current set point for a 2-hour period after which it will return to the previous mode. Automatic (schedule programs) Set the desired temperature or quickly press or to use a predefined set point. Remote Unoccupied Set the desired temperature. All buttons are locked except for the buttons., Day, Hour and Minute The yellow LED on top of the display remains on, but the icon disappears. #10b. Fan Modes (Fan button) The Phone-A-Stat thermostat is equipped with a fan button offering two fan settings: On and Automatic. When On: ( ) the fan runs continuously. The Automatic setting allows the fan to run only during heating or cooling cycles. #10c. Balance Point Cut-Off The Phone-A-Stat thermostat requires a Remote Temperature Interface and the outdoor sensor to use this function. This option allows the user to define the temperature set point at which the heat pump compressor will be cut-off and only the auxiliary heat will be used when heating is required. The auxiliary heat is automatically activated on a call for heat when the outdoor temperature falls below the balance point. The heat pump compressor will be re-activated only when the outdoor temperature is at least 1 C (1 F) higher than the cut-off set point. The default balance point cut-off is -8 C (17 F). Press and hold Heat/Cool until the set point is displayed. Use the buttons to set the new balance point. Press Heat/Cool to exit. 4. #10D. Automatic Changeover When the AUTO mode (automatic changeover) is selected, the thermostat analyzes the system s requirements and automatically alternates between HEAT and COOL mode to provide occupant comfort. There are two ways to use the automatic changeover mode: Fixed Set point When you set the temperature using the arrow buttons, the Phone-A-Stat uses this unique temperature set point for temperature control. The thermostat automatically switches to HEAT mode when the ambient temperature drops under the temperature set point whereas the COOL mode is activated when the temperature rises above the temperature set point. In order to switch modes, the ambient temperature must be maintained over or under the control band for more than 12 minutes. Predefined Set point ( or ) When a predefined set point button is selected, the Phone-A-Stat thermostat uses the corresponding COOL and HEAT set point temperatures for temperature control. The thermostat automatically switches to COOL mode when the ambient temperature rises above the COOL set point whereas the HEAT mode is activated when the ambient temperature drops below the HEAT set point. In order to switch modes, the ambient temperature must be maintained over or under the set point control band for more than 12 minutes. P/N L1159 Page 10 of 11
