TEC20x6(H)-4 and TEC20x6H-4+PIR Series Wireless Thermostat Controllers with Dehumidification 
Capability, Fan Control, and Occupancy Sensing Capability 

12

Note:

Pressing the 

FAN

 key during configuration 

restarts the list of displayed parameters at the first 
parameter listed in Table 6.

When the thermostat controller is in the Installer 
Configuration Menu and left unattended for 
approximately 8 seconds, the thermostat controller 
reverts to the Status Display Menu.

Configuring Inputs BI1, BI2, and UI3

When BI1 and BI2 are configured for an alarm 
condition, an alarm condition displays locally when the 
input closes. An alarm message is included on the 
scrolling Status Display Menu and when the message 
is displayed, the backlight momentarily lights up.

The UI3 input provides changeover of hot/cold water 
switching or supply air temperature monitoring at the 
thermostat controller.

Each input can be configured to the Selection Options 
included in Table 6.

Configuring the Sequence of Operation 
(SeqOpera) 

Choose the appropriate sequence of operation. The 
modes presented are user-dependent on the sequence 
of operation selected. For two-pipe applications using a 
changeover sensor, choose the selection option 

(0): Cooling Only

. Changeover occurs between 

Cooling Only

 and 

Heating Only

. See Figure 16 

through Figure 21 for sequence of operation examples.
