[. . . ] · Recovery ramping control automatically optimizes equipment start times based on building load. · Thermostat Interface Module (TIM) connections to thermostat from PDA for advanced configuration, programming, etc. · Universal VersaguardTM Thermostat guards available. 63-2604 · Auxiliary subbase contact typically interface with a Honeywell Economizer System (for total rooftop control integration) or act as dehumidification output. SETTINGS Using Thermostat Keys The thermostat keys are used to: · set current time and day, · program times and setpoints for heating and cooling, · override the program temperatures, · display present setting, · set system and fan operation, · perform simple configuration. 1 for keypad information. Features Available via PDA Configuration · 365 day clock with holiday programming. [. . . ] -- Em Heat: Auxiliary heat serves as first stage. Compressor stages are locked off. Setting System and Fan System default setting is Auto. The fan default is set so the fan operates continuously during: -- Occupied periods, -- Heating and cooling equipment stages in Not Occupied and recovery periods. NOTE: Use System and Fan keys to change settings. Fan Settings -- On: Fan operates continuously in occupied and standby periods. Fan cycles with call for heat or cool during not occupied periods. -- Auto: Fan cycles with call for heating or cooling during occupied, standby, and not occupied periods. NOTE: This is further modified by selection of conventional or electric heat. 4 63-2604 PROGRAMMING The thermostat operates at the Occupied temperature setting unless the thermostat is programmed. The program has four settings: -- Occupied heat. The thermostat can be set for two Occupied and two Not Occupied times for each day of the week (28 independent time settings). The Temporary Occupied key provides quick setpoint changes for increased comfort during Not Occupied periods. The Temporary Not Occupied key provides energy efficient operation for extended periods of time. IMPORTANT Programming the thermostat with the keypad requires 24 Vac (turn on system power).

Repeat steps 1 through 3 for all the start times to be cleared. Press Run Schedule. Temperature Setpoints Setpoint Limits The setpoint temperature range is 40°F to 90°F (4°C to 32°C) for heating and 45°F to 99°F (7°C to 37°C) for cooling. NOTES: The ranges mentioned can be limited based upon setpoints and stops: 1. The greater of the Minimum Heat Stop and the Not Occupied Heat setpoints determines the lowest setting to which the occupied heat setpoint can be adjusted: Stop/NotOcc OccHeat (OccCool - 2). The lesser of Maximum Cool Stop and Not Occupied Cool setpoints determines the highest setting to which the occupied cool setpoint can be adjusted: Stop/NotOcc OccCool (OccHeat + 2). The Maximum Occupied Heat Setpoint is limited by Occupied Cool Setpoint ­ 2. The Minimum Occupied Cool Setpoint is limited by the Occupied Heat Setpoint + 2. 9 63-2604 Programming Temperature Setpoints 1. Press up or down until the desired temperature is displayed. Press up or down until the desired temperature is displayed. [. . . ] If the number of days is set to zero, no temporary change takes effect.
