When used with a BAYBASE006A or BAYBASE008A subbase, the thermostat is automatically configured for conventional heat/cool applications. When used with a BAYBASE007A subbase, the thermostat is au- tomatically configured for heat pump applications. The BAYSTAT040A and ASYSTAT705A are also field configurable for automatic or manual changeover between heating and cooling. The system selections are made by keyboard entry. All thermostats require a common wire to 24 VAC supply power. RECYCLING NOTICE: If this control is replacing a control that contains mercury in a sealed tube, do not place your old control in the trash. Contact your local waste management authority for instructions regarding recycling and the proper disposal of the old thermostat. Installation When Installing this thermostat: 1. Read these instructions carefully. Failure to follow them could damage the thermostat or cause a hazardous con- dition. 2. Check the ratings given in the instructions and on the thermostat to make sure the thermostat is suitable for your application. 3. The installer must be a trained, experienced service tech- nician. 4. After installation is complete, check out thermostat opera- tion as provided in these instructions. Mounting Thermostat on Subbase The thermostat mounts on the subbase after it is installed. 1. Engage tabs at the top of the thermostat and subbase. See Figure 1. 2. Press lower edge of case to latch. Note: To remove the thermostat from the wall, first pull out at the bottom of the thermostat; then remove the top. Figure 1 - Mounting the thermostat on the subbase Installer's Guide Customer Property: Contains wiring and service informa- tion. Please retain. 2 Installation Settings Using Thermostat Keys The thermostat keys are used to: - set the current time and day, - program times and setpoints for heating and cooling, - override the program temperatures, - display present setting, - set system and fan operation, - configure Installer Setup, - check Installer Self-Test. See Figure 2 for key information. Figure 2 - Thermostat key locations and descriptions Setting the System and Fan (select models) The system default setting is Heat. The fan default is set so the fan operates with the heating or cooling equipment in Occupied and Unoccupied mode. Use the System and Fan keys to change the settings. The system settings are: Em Heat (BAYBASE007A): Emergency heat relay is on continuously. Thermostat cycles highest stage of heat. Cooling system is off. Compressor is de-ener- gized. Heat: Thermostat controls the heating. Off: Both heating and cooling are off. Cool: Thermostat controls the cooling. Auto: Thermostat automatically changes between heating and cooling operation depending on the indoor temp- erature. The default fan setting is: Auto: - fan turns on only when there is a call for heating or cooling. See programming for other options. Setting Temperature Refer to Table 1 for the default temperature setpoints. See Table 2 for complete instructions on changing the setpoints. Table 1 - Default Temperature Setpoints Control Occupied Unoccupied Heating 70oF (21oC) 55oF (13oC) Cooling 78oF (25.5oC) 90oF (32oC) 3 Installer Setup Note: For most applications, the thermostat factory-settings do not need to be changed. Review the factory-settings in Table 2 and if no changes are necessary, go to the Installer Self-Test section. The Installer Setup is used by the installer to customize the thermostat to specific systems. Installer Setup numbers are listed in Table 2. The table includes all the configuration op- tions available. A combination of key presses are required to use the In- staller Setup feature. - To enter the Installer Setup mode, press and hold the Heat/Cool Settings key with both the increase up key and the down decrease keys until the first number is dis- played. All display segments appear for approximately three seconds before the number is displayed. See Figures 3 and 4. Figure 3 - Display of all the segments of the LCD.

The Installer Setup is automatically exited if no key presses are made for four minutes. Installer Setup numbers are listed in Table 2. HEAT PUMP AND ELECTRIC HEAT SYSTEMS MUST BE CONFIGURED IN INSTALLER SETUP 2 TO PRE- VENT EQUIPMENT DAMAGE CAUSED BY THE SYS- TEM RUNNING WITHOUT THE FAN. IMPORTANT: Only configurable numbers are shown on the device. Example: If thermostat does not have a system key, Installer Setup Number 12 will not be displayed. Review Table 2 factory-settings and mark any desired changes in the Actual Setting column. When Installer Setup is complete, review the settings to confirm that they match the system. 4 Installation Table 2 - Thermostat Installer Setup Options Installer Factory Optional Setup # Defaults Description Settings Description Not Used 1 -- -- -- -- Fan 2 1 Electric heat applications 0 Conventional applications Operation where thermostat where equipment controls controls fan fan operation in heat operation in heat mode. mode Heating 3 2-Conventional T’stat Stages of Heat 2-Conventional T’stat 0 - No heating Stages 3-Heat Pump T’stat 3-Heat Pump T’stat 1 - One stage of heat 2 - Two stages of heat 3 - Three stages of heat Heat 4 6 Stage 1 - 6 cph. 3, 4, 6, 8 or 9 3 - 3 cph used for hot water Cycle 5 6 Stage 2 - 6 cph. systems or high Rate 6 6 Stage 3 - 6 cph. efficiency furnaces. 7 4 4 - 4 cph used for Emergency heat relay is conventional systems on continuously.
