This thermostat is designed to work on the following systems: • Gas - Standing Pilot • Gas - Electronic Ignition • Gas - Fired Boilers • Gas - Milivolt Systems • Oil - Fired Boilers • Oil - Fired Furnace • Electric Furnace • Electric Air Conditioning This thermostat will NOT control single-stage or multi-stage heat pumps or 110/220 V baseboard electric heating systems. 2. temperature Range This thermostat can be set between 45°F and 95°F (7°C and 35°C). However, it will display room temperatures from 30°F to 99°F (0°C and 37°C). “HI” will be displayed if the temperature is higher than 99°F (37°C), and “LO” will be displayed if the temperature is lower than 30°F (0°C). This thermostat will automatically cutoff in Heat mode if the temperature rises above 95°F (35°C), and automatically cutoff in Cool mode if the temperature drops below 45°F (7°C). 3. Compressor protection This thermostat provides a 3.5 minute delay after shutting off the cooling system before it can be restarted. This feature will prevent damage to your compressor caused by rapid cycling. It does not prevent a rapid compressor restart due to short power outages. 4. Battery Warning Two fresh AA alkaline batteries should provide well over one year of service. However, when the batteries become drained, the Low Battery Indicator will flash on the display. When this message occurs, install new alkaline batteries. You have approximately 1 minute to change the batteries and keep the thermostat’s settings. Once the batteries have become too low to ensure proper operation, your system will be turned Off, and the display will be cleared except for flashing Low Battery Indicator on the LCD display. CAUTION: When only the battery icon flashes on the display, the ther- mostat is shut down, and your system will no longer operate. In this condition, there is no temperature control of your dwelling. NOTE: If you plan to be away from the premises over 30 days, we recommend that you replace the old batteries with new alkaline batteries prior to leav- ing. 5. notes This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency en- ergy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. featuRes What You need This thermostat includes two #8 slotted screws and two wall anchors for mounting. To install your thermostat, you should have the fol- lowing tools and materials. • Slotted Screwdriver(s) • Small Philips screwdriver • Hammer • Electric drill and 3/16” bit • Two 1.5 V (AA) size alkaline batteries Remove old thermostat CAUTION: Do not remove any wiring from existing thermostat before reading the instructions carefully. Wires must be labeled prior to removal. IMPORTANT! Turn off the power to the furnace at the main power panel or at the furnace. Remove existing thermostat cover and thermostat. See Figure 1. Some ther- mostats will have screws or other locking devices that must first be removed. Once the wall mounting plate is exposed, look for wires. If wires are not visible, they may be connected to the back of the wallplate. Again, look for screws, tabs, etc. Some models have doors that open to expose wires and mounting screws. See Figure 1.

Operation Theory – Transmitter - Model 42996 Model 42996 Thermostat RF transmitter operates the associated receiver/thermostat by means of a pulse modulated radio/frequency signal operating at 350 MHz. The transmitter’s two buttons permit the user to adjust the temperature setting up or down. A four-position DIP switch permits the user to encode the signal for one of 16 possible combinations. The signal pattern consists of a series of long or short pulses as follows: The duration of each pulse, along with the period between the bursts, is detailed in the test report. The antenna is integrated and not adjustable or detachable by the user. Output power and frequency are fixed and not adjustable by the user.
