TEC20x6(H)-4 and TEC20x6H-4+PIR Series Wireless Thermostat Controllers with Dehumidification

Capability, Fan Control, and Occupancy Sensing Capability

9

Light-Emitting Diodes (LEDs)

Three LEDs are included to indicate the fan status, call 
for heat, or call for cooling:

The fan LED 

 is on when the fan is on.

The heat LED 

 is on when heating is on.

The cool LED 

 is on when cooling is on.

The Status LED, located beneath the cover, flashes at 
5-second intervals to provide indication of the network 
status of the thermostat controller. See Table 3.

Integrated PIR Sensor – 
TEC20x6H-4+PIR Series Thermostat 
Controllers

The integrated PIR sensor allows for automatic 
switching between fully adjustable Occupied and 
Stand-By temperature setpoints without user 
interaction. This feature generates incremental energy 
savings during scheduled occupied periods while the 
space is unoccupied.

Backlit Liquid Crystal Display (LCD)

The thermostat controller includes a 2-line, 8-character 
backlit display. Low-level backlighting is present during 
normal operation, and it brightens when any user 
interface key is pressed. The backlight returns to low 
level when the thermostat controller is left unattended 
for 45 seconds.

Status Display Menu

 

The Status Display Menu displays during normal 
operation. This menu scrolls through several 
parameters:

Room Temperature

Room Temperature and Humidity (TEC2036-4, 
TEC2036H-4, TEC2036H-4+PIR, TEC2056-4, 
TEC2056H-4, and TEC2056H-4+PIR models)

Note:

For models with dehumidification capability, 

the default setting is no humidity reading on the 
display (

%RH disp 

parameter is set to 

off

.) The 

%RH disp 

parameter must be set to 

on 

to display 

the current humidity reading.

System Mode

Occupancy Status (Occupied/Unoccupied/
Override) 

Applicable Alarms – The backlight lights up as an 
alarm condition is displayed.

Note:

An option is available within the Installer 

Configuration Menu to lock out the scrolling display and 
show only the Room Temperature parameter.

Dehumidification Operation – 
TEC2036(H)-4 and TEC2056(H)-4 Thermostat 
Models

Upon detection of room humidity above the adjustable 
humidity setpoint as sensed by the integral humidity 
sensor, dehumidification activates.

Note:

Dehumidification operation functions only in the 

Cooling mode; dehumidification operation does not 
function in either the Off or the Heating mode.

Note:

A central network command can globally 

lock out dehumidification operation to all thermostats.

If the room temperature resides in the deadband 
between the Heating and Cooling setpoint:

the thermostat forces the fan to low speed

the chilled water valve opens to the specified 
maximum value set by 

CoolMax

the thermostat stages Heating to maintain the room 
temperature at the Cooling setpoint, as sensed by 
the thermostat

If the room temperature falls below the current Heating 
setpoint, the thermostat disables dehumidification 
operation.
