Pre-Installation

This section provides the following pre-installation information:
• Location considerations
• Height requirements
• Mounting surfaces
• Recommended wire lengths

Location Considerations
Placement of the sensor is critical to proper operation. When selecting a location, avoid the following:

• Areas of direct sunlight
• Areas in the direct airstream of air diffusers
• Exterior walls and other walls that have a temperature differential between the two sides
• Areas that are close to heat sources such as sunlight, appliances, concealed pipes, chimneys, or other heat-generating equipment
• Drafty areas
• Dead spots behind doors, projection screens, or corners
• Walls that are subject to high vibration
• Areas with high humidity
• High-traffic areas (to reduce accidental damage or tampering)

Height Requirements
It is recommended that you mount the back plate at a maximum distance of 54 inches above the floor. If a parallel approach by a person in a wheelchair is required, reduce the maximum height to 48 inches.
Note: Consult section 4.27.3 of the 2002 ADA (Americans with Disability Act) guideline, and local building codes, for further details regarding wheelchair requirements.

Mounting Surfaces
Using the hardware provided, mount the back plate to a flat surface such as sheetrock or plaster, or an electrical junction box. The sensor must be mounted plumb for accurate temperature control and to ensure proper air movement through the sensor.

• If mounting onto sheetrock or plaster, use the plastic threaded anchors (pre-drilling holes is not usually necessary) and the two M3.5 x 20 mm mounting screws.
• For mounting onto an electrical junction box, use the two 6-32 x 3/4 in. screws.
• If you are replacing a horizontally mounted sensor and need to cover an opening in the wall, use the adapter kit (p/n BAYMTPL103A).

	If the colon on the time clock is flashing, the system is powered up.
	If the cooling symbol is flashing, the system is in cooling mode.
	If the heating symbol is flashing, the system is in heating mode.

Default Operation

If the sensor has not been scheduled, it operates with the following default settings:

• For sensors configured to operate with CV or HP units:
• Occupied
• Heating setpoint: 68ºF (20ºC)
• Cooling setpoint: 74ºF (23.3ºC)

For sensors configured to operate with VAV units:

• Occupied
• Warm-up setpoint: 68ºF (20ºC)
• Supply-air heating setpoint: 100ºF (37.8ºC)
• Supply-air cooling setpoint: 55ºF (12.8ºC)

Setpoint Only Display

You can configure the zone sensor to present setpoints instead of the space temperature on the main display. To display setpoints instead of space temperatures, follow these steps:

1. Begin at the home screen
2. Press the and simultaneously for four seconds. The active setpoint now appears instead of the space temperature. Setpoint presentation is indicated by an arrow in the upper left corner of the display (see Figure 6).
3. Press or toggle between the heating and cooling setpoints.
4. To return to showing space temperature on the display, press the and simultaneously for four seconds.

Weekly Operating Schedule Forms
The easiest scheduling procedure is sequential. You should complete the schedule set up for each period of the day, in order, before you move on to the next day. For instance (refer to Figure 7 below), once the schedule is opened, you will start with Monday and the Morning period (1). Set the start time, occupancy, heating and cooling setpoints, and fan operation if applicable. Once you finish with the morning period, you will complete the Day period (2)(same settings as for Morning…start time, occupancy, etc.). You should complete all available periods for Monday before moving on to Tuesday (5). The same rules apply for Tuesday. Each period should be set in order before moving on to Wednesday. This applies to all days in the schedule. You can use Table5, p.25 to create a weekly operating schedule for sensors configured for CV or HP units. For sensors configured as VAV, see Table 6, p.26. Figure 6. Setpoint only display

Figure 7.Sequential completion of a weekly operating schedule

You can use Table 5, p.25 to create a weekly operating schedule for sensors configured for CV or hP units. For sensors configured as VAV, see Table 6, p.26.

Table 5. The weekly operating schedule for sensors configured for CV or HP units

 

This applies to CV/HP only and only if the programmable fan is enabled.

Maintenance and Troubleshooting

This section describes maintenance and troubleshooting for the programmable zone sensor.

Error Codes
An error code indicates that technical assistance may be required.
Note: On the display, error codes toggle with the clock.

E1	Heat failure	Indicates that there is an error in the heating system.
E2	Cool failure	Indicates that there is an error in the cooling system.
E3	Test mode	Indicates that the system is operating in test mode.
E4	Fan failure	Indicates that a fan failure has occurred and service is required.

Conducting a Self-Test

Starting from the home screen, press the Test/Configuration button. The following sequence appears on the display:

• The display lights
• All of the symbols appear for 2
• The software version appears for 2
• The number of years in service appears for 2
• The home screen appears and the light

Check Filter Timer

Check filter interval is a configuration option that allows you to set a timer that is adjustable in 1- day increments. After the number of selected days passes, the check filter time symbol will flash on the displayThe symbol is a reminder to check the condition of the filter. To reset the timer, press both  and  for 2 seconds. The check filter symbol will disappear.

Troubleshooting Table

Problem	Solution
Display does not come on.	Check the 24 Vac power supply at terminals 11 and 14 at the sensor. Verify that the terminal block is properly positioned on its pins.
No communication to the unit controller.	Check for 22–32 Vdc between terminals 11 and 12 at the sensor. Check wiring if no voltage is present.
SH appears in the temperature location on the display and “Off” flashes.	Verify that Option 11 is set correctly for CV/HP configurations (option 10 for VAV configurations): •   If set to 1, check the wiring from the remote sensor at terminals S1 and S2 for a shorted condition. •   If set to 0, the on-board thermistor has shorted and the sensor must be replaced.
OP appears in the temperature location on the display and “Off” flashes.	Verify that option 11 is set correctly for CV/HP configurations (option 10 for VAV configurations): •   If set to 1, check the wiring from the remote sensor at terminals S1 and S2 for an open circuit condition. •   If set to 0, the on-board thermistor is open and the sensor must be replaced.
Zone temperature does not appear.	Verify that option value 1 has been selected for option 13 (CV/HP configurations). Verify that option value 1 has been selected for option 12 (VAV configurations).
Keypad does not respond.	Check to see if the lock symbol is on. To unlock the keypad, press and hold the left and right arrow keys for 4 seconds.
The fan is set to the On position, but the fan is not running (CV/HP configurations only).	Verify that the value for option 10 is set correctly (CV/HP configurations only). •   If set to 1, check that the fan is set to On for the current period of day. •   If set to 0, check the value for Option 6. If it is set to 1, the fan will always operate in Auto mode for unoccupied periods.
The system is operating before the scheduled period begins (CV/HP configurations only).	If option 7 is set to 1, the computed recovery option is enabled. This allows system operation to begin before the scheduled occupied period, so that the occupied temperature setpoint is reached efficiently.
The check filter symbol flashes.	To reset the timer, press the up and down arrows for 2 seconds. The check filter symbol will disappear. If this function is not desired, or a different interval is desired, set option 11 (VAV configurations) or option 12 (CV/HP configurations) to a different value.
The number “99” flashes.	Space temperature is above the measurable range.
The number “32” flashes.	Space temperature is below the measurable range.
