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.
