The fan operates as a default ON/AUTO selection that works the same way as our CommercialPRO TB7220 thermostat. There is only one fan relay output that is activated. If PTAC or fan coil thermostat application modes are enabled in ISU 170, then ISU 347 fan ramp algorithm is available for installer setup selection. The fan ramp algorithm will automatically calculate the appropriate fan speed that is needed to meet the proportional band requirements to speed up setpoint satisfaction. When the setpoint is satisfied it will revert to the lowest fan speed setting to conserve energy. The thermostat comes factory default with the fan ramping algorithm enabled (ISU 347). This gives the user the ability to select Auto-Lo-Med-Hi option in ISU 348 or Auto only option in ISU 348. Auto sets the thermostat into the fan ramping algorithm mode and automatically sets the sufficient speed for PI control. Auto also automatically shuts the fan off when there is not a call for heating or cooling. If the user decides to disable ISU 347, then the fan will only have Lo-Med-Hi option available. If ISU 347 is not enabled, then ISU 348 does not appear as a user selection choice. If ISU 347 is enabled, then ISU 349 is available as a selection choice. The user can select either a 2 hour or 4 hour timer fan reset function. The fan will reset from a constant on speed to Auto mode after the time period expires. If ISU 347 is not enabled, then ISU 349 does not appear as a user selection choice. Equipment Sequence Operations (ISU 170) Heat Pump and Conventional Heat Pump and conventional use a single fan speed. The single fan speed label is the G terminal relay output. Display on the thermostat for these modes will give the Fan On/Auto option. There is no fan ramping algorithm, ISU 347, 348, 349 are not available. sensor enabled, the thermostat screen system mode will lock on heat or cool (whatever the changeover sensor is communicating to the thermostat). If ISU #340 does not have a changeover sensor enabled, then the system mode from the thermostat screen can manually be adjusted between heat or cool. It follows the fan sequencing described above with ISU 347, 348, 349. 2 pipe with reheat - 2 pipe modes do not contain the ability to have automatic changeover. They are manual changeover only. The thermostat will have a priority when choosing a system mode (heat or cool). When ISU #340 has a 2 pipe changeover sensor enabled, the thermostat screen system mode will lock on heat only. When the 2 pipe changeover sensor is sensing cool mode, the user can adjust to heating mode which will bring on the auxiliary heat. If ISU #340 does not have a changeover sensor enabled, then the system mode from the thermostat screen can manually be adjusted between heat or cool. It follows the fan sequencing described above with ISU 347, 348, 349. Operating Sequence The thermostat energizes specific terminal(s), depending on the demand for heating, cooling or fan. The thermostat screen shows the time, inside temperature, system and fan selections. Additional indicators are shown when the heating, cooling or fan is energized.

Preoccupancy purge (ISU 185) This feature is available only when the thermostat is configured as a programmable schedule and when a fan is used. The fan will run 1-3 hours before the occupied schedule starting time to circulate air. Override Button, Temporary Override (Duration Limit ISU 535) While in the programmable schedule mode, an override button is available to perform temporary override control. The default override time can be configured through ISU 535. Lockout configuration via ISU 670 can provide restrictions on access to setpoint changes, system changes, and schedule changes. No remote setback The remote setback feature only works in the nonprogrammable mode. Override (Optional) The override feature is optional in the non-programmable mode. The override can be configured through ISU 342. When the override is activated in the non-programmable mode it will temporarily override to a new setpoint until the end time expires. Remote Setback Remote Setback is available (ISU 340). Occupancy sensors, manual time clock inputs, and DDC night setback can be used to provide inputs to setback the thermostat. Unoccupied heating (ISU 343) and unoccupied cooling (ISU 346) setpoints are available to configure the setback setpoints. Setting Temperature Overrides 2.

The C7189U can be used to provide one remote sensor input or as a temperature averaging network with multiple TR21 Sensors connected, as shown in Fig. 28. Checkout Temperature Recovery The thermostat is equipped with a feature to eliminate guesswork when setting a schedule. That is, the user need not know the amount of time for the HVAC system to bring the space to temperature (without overshoot) prior to the scheduled time.The thermostat manages that automatically. Simply set the program schedule to the desired time to have the space at comfort temperature. In addition, program the temperature to this comfort temperature. The thermostat activates the heating or cooling at the proper time to reach the scheduled temperature at the scheduled time. NOTE: The setpoint changes gradually to use economical stages and avoid overshoot. For best results, allow C7189U Wall Mount Temperature Sensor to absorb the air moving through the room for a minimum of twenty minutes before taking a resistance measurement. With an accurate thermometer (±1°F [0.5°C]) measure the temperature at the sensor location, allowing time for the thermometer to stabilize before reading. To verify sensor resistance, remove one wire from one of C7189U wiring terminals. Use an ohmmeter to measure the resistance across the sensor. Then compare sensor accuracy with the temperature/resistance curve in Fig. 40. 220K For example—the space will be occupied at 8:00 AM and the desired temperature is 70°F. Set the OCC 1 period for 8:00 AM and 70°F. The thermostat turns on the heat prior to 8:00 AM to raise the temperature to 70°F by 8:00 AM. 190K RESISTANCE (OHMS) 160K The thermostat provides an alert that the heating or cooling system is coming on before a scheduled time by displaying “Recovery” on the screen. Minimum-Off Timer Compressor Protection The thermostat has an adjustable Minimum-Off Timer that can be set from zero to five minutes (Factory Setting—five minutes). The Minimum-Off Timer can be bypassed through the Installer System Test or it can be bypassed permanently by setting the Minimum-Off Timer to 0 minutes in the Installer Setup. The Minimum-Off Timer is activated after the compressor turns off: — If the thermostat is system powered (common wire), the Minimum-Off Timer is also activated upon initial startup and after power interruptions. — If there is a call for cooling or heating during the MinimumOff Time, the thermostat displays “Wait.” — When the Minimum Off Timer expires, “Cool On” or “Heat On” (heat pumps only)” appears solidly in the display and the compressor and fan turn on. Temperature Sensor Operation and Checkout Allow outdoor or indoor temperature sensor to absorb the air for a minimum of five minutes before taking a reading.
