TB7100A1000 MULTIPRO™ MULTISPEED AND MULTIPURPOSE THERMOSTAT

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 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.

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 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. See Tables 8 and 9 for specification information.

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.

OVERRIDE

Changes temperature setting until the next period takes effect. For use during Unoccupied periods.

1. Press OVERRIDE. The settings change by default to the next Occupied period.

NOTE: Changes are limited to those allowed by the

lockout level.

2. Press Up or Down arrow to change the override temperature, and NEXT to adjust override time.

HOLIDAY

Changes temperature setting for a designated number of days. Press MORE and then HOLIDAY. The screen shows “Hold Until 1 DAYS”.

1. Press Up or Down arrow to change the temperature desired for the thermostat to override the schedule.

2. Press NEXT to change the desired days for the duration of the holiday.

3. To cancel the Holiday Override early, press CANCEL.

Fan Status Displayed on Main Screen

When the thermostat is running the fan, the fan blade symbol

appears next to FAN to indicate the thermostat has the fan

on.

NOTE: If the thermostat is not controlling the fan—typical for

many gas, forced-air heating systems—the fan blade symbol will not appear even though the fan may be running.

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

There are three temperature override options: — Hold Temperature Until — Override, and — Holiday.

HOLD TEMPERATURE UNTIL

Holds the temperature temporarily until the time set by the user, or the next scheduled period time.

1. Press the Up or Down arrow next to the temperature to adjust. The Hold Until time appears on the screen. The time defaults to the next scheduled period start time

2. Press NEXT to adjust the time for the thermostat to resume schedule.

NOTE: The installer setup can limit the length of time

for an override to 1, 2, 3, or 4 hours beyond the current time.

3. Press DONE or wait 5 seconds.

4. Press CANCEL or SCHEDULE to cancel “Hold Tempera-

ture Until” and resume the schedule.

Replacing Batteries

Not all thermostat models require batteries. If the thermostat has batteries, a low battery warning (see Fig. 38) flashes on the main screen for approximately 30 days.

NOTE:

— If batteries are not replaced when the Low Battery

warning is flashing, the LO batt screen displays continuously and the thermostat stops operating until batteries are replaced.

— The thermostat has a low battery indicator.

However, it is recommended that the batteries be replaced once each year. Do this to prevent leakage and prevent the thermostat and HVAC system from shutting down due to lack of thermostat battery power.

Reading Remote Indoor Temperature

If connected to an installed remote indoor temperature sensor, the thermostat displays the indoor temperature from the remote sensor(s).

— Pressing a locked key prompts the screen to indicate

LOCKED for five to seven seconds.

— Pressing an unlocked key with LOCKED shown removes

LOCKED from the display.

— HOLIDAY and OVERRIDE options are available in all partial

lockout levels.

— Pressing HOLIDAY sets the temperature to the Unoccupied

setting for the selected period of time. The next Occupied period switches back to the program settings.

— Pressing OVERRIDE sets the temperature to the Occupied

setting for the selected period of time. The next Unoccupied period switches back to the program settings.

— To cancel the temperature override and follow the

programmed schedule, press CANCEL.

PARTIAL LOCKOUT 1

This mode locks out schedule and system changes.

— User can change the temperature setpoint and fan settings,

but cannot change schedule or system settings.

— The temporary changes last until next scheduled period.

The screen displays that time.

— To unlock the screen, see Advanced Settings section.

PARTIAL LOCKOUT 2

This mode locks out schedule, system and fan changes.

— User can change the temperature setpoint, but cannot

change schedule, system, or fan settings.

— The temporary temperature change lasts until next

scheduled period. The screen displays that time.

— To unlock the screen, see Advanced Settings section.

PARTIAL LOCKOUT 3

This mode locks out schedule, system, fan, and temperature setpoint settings.

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 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.

The thermostat provides an alert that the heating or cooling system is coming on before a scheduled time by displaying “Recovery” on the screen.

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

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.

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.

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. See the Sensor instructions for more information.

NOTE: The C7189U, TR21 and TR21-A Temperature

Sensors are calibrated at the factory and cannot be recalibrated in the field.

C7189U Remote Indoor Temperature Sensor

Operation

When installed with Thermostat ISU 0340 set to 3, the remote inside temperature is displayed on the Thermostat Home Screen as Inside Temperature. The thermostat internal temperature sensor is not used.
