    72 hrs. INSTALLATION CONSIDERATIONS POWER Note that all TSTAT models require no batteries and are not "power stealing". They do require 24VAC (R and C terminals) to be connected for proper operation. Thermostat will not operate without these 2 connections.

    II. SET DIP SWITCHES There is a 4 section DIP switch within the thermostat which must be properly set by the installer. It is easiest to set these 4 switches before the thermostat is mounted to the wall, so STOP and complete the following steps: 1.

    B. To Enter Configuration Mode: Press and hold FAN button for approximately 10 sec until COOL set point display indicates a flashing 01. The thermostat is now in configuration mode. It will automatically exit this mode if no button is pressed for 3 minutes. Pressing END button will exit configuration mode immediately.

    V. CHECK THERMOSTAT OPERATION Before doing the checkout, press HOLD button to turn on HOLD icon, locking thermostat in hold mode. This will assure set points don’t change during the checkout. Outputs for each stage of operation are listed in Table 2. In the table, the actual use of each terminal is underlined for terminals having double use.

    If set point is raised more than 5° above room temperature, the staging timer is defeated and the thermostat will call for higher stages within 5 sec. Use this method if there are only 2 stages of heat. If more than 2 stages of heat are available, do not use this method because once the demand exceeds 5°, the thermostat may jump to the highest stage.

    1. The AC model thermostat can only control 1-stage cool and 1-stage heat. Dip Switch-C on has no controlling function and can either be ON or OFF. 2. HP and 2S model thermostat MUST have Dip Switch-C ON when installed in air conditioner applications. If required, second-stage heat is controlled by O/W2.
