OPERATION
- Fan Sequence Operations (ISU 347, 348, 349)
If heat pump or conventional application modes are enabled in ISU 170, then ISU 347 is not available for fan ramp algorithm. 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 is available for installer setup selection.
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 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 will be G, located on the G1 terminal relay output. Label should read G/Gl to help out the installers. 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. - PTAC
PTAC modes 10 and 11 will have the same selection options available as the heat pump selection options. The only difference is that the PTAC options have a Lo and Hi speed fan output instead of single speed output and that it follows the fan sequencing described above with ISU 347, 348, 349. - 4 Pipe
4 pipe is treated similar to 1H/1C conventional. It follows the fan sequencing described above with ISU 347, 348, 349. - 2 Pipe
There are two different 2 pipe modes – 2 pipe only and 2 pipe with reheat. - 2 pipe only – 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 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 changeoversensor 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.
- Special Programmable Mode Functions
Installer Setup 160 allows the thermostat to be configured for either a mode with a programmable 7 day schedule or as a non-programmable thermostat. - 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.
Special Non-Programmable Mode Functions
- 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 thethermostat. Unoccupied heating (ISU 343) and unoccupied cooling (ISU 346) setpoints are available to configure the setback setpoints.
System Settings
- Heat—Thermostat controls the heating system.
- Off—Both heating and cooling systems are off. Fan is turned off.
- Cool—Thermostat controls the cooling system.
- Auto—Thermostat automatically changes between heat and cool operation, depending on indoor temperature.
Fan Settings
- Auto —Fan runs only when heating/cooling system is on.
- On—Fan runs continuously.
Table 5 shows default program settings. See Owner’s Guide for complete instructions to change the program.

- 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 Minimum-Off 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.
Indoor Temperature Sensor
Allow indoor temperature sensor to absorb the air for a minimum of five minutes before taking a reading. See the Sensor instructions for more information.
