User manual HONEYWELL T7300

[. . . ] · Convenient overrides allow temporary setpoint changes. 2 · Intelligent FanTM feature energizes fan continuously in the Occupied periods. Fan can also be configured for conventional heat or electric heat fan operation. · Remote sensor capability for temperature (including outdoor air and discharge air) and humidity sensors. · 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. · Ambient lockout (with outdoor sensor). Setting Temperature Refer to Table 1 for default temperature setpoints. See Programming section for complete instructions on changing these. 3 63-2604 Table 1. Control Occupied Not Occupied Standby 67°F (19°C) 78°F (26°C) Heating 70°F (21°C) 55°F (13°C) Cooling 75°F (24°C) 85°F (29°C) System Settings -- Auto: Thermostat automatically changes between heating and cooling based on sensed indoor temperature. 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. 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 Run Schedule. Temperature Setpoint Overrides IMPORTANT -- Setup determines Occupied override duration. NOTE: To cancel Override and immediately return to the program, press Run Schedule. T7770 Setpoint Knob A T7770 setpoint knob can remotely adjust the T7300 setpoint. NOTES: -- -- 10 During override, only occupied and standby heat setpoints, and cool setpoints are adjusted. The maximum adjustment is ±5°F. 63-2604 -- With a disconnected or failed T7770, or a T7300 set for local temperature sensing, offset is zero. Using Temporary Not Occupied Override The Temporary Not Occupied Override fixes the device to operate in Not Occupied mode for a number of days (between 1 and 99) without changing the programming saved in memory. If the number of days is set to zero, no temporary change takes effect. [. . . ] The maximum adjustment is ±5°F. 63-2604 -- With a disconnected or failed T7770, or a T7300 set for local temperature sensing, offset is zero. Using Temporary Not Occupied Override The Temporary Not Occupied Override fixes the device to operate in Not Occupied mode for a number of days (between 1 and 99) without changing the programming saved in memory. If the number of days is set to zero, no temporary change takes effect. If the number of days is set just below zero, the display for days is "---" (an indefinite override). To turn off this override, you must press Run Schedule. Using Temporary Occupied Override The Temporary Occupied Override can be used when the T7300 is in Not Occupied or Standby mode. [. . . ]
