Optional Occupancy Detection Equipment Operation

Optional Occupancy Detection Equipment Operation

The T180 thermostat can be used with optional S200 series 
occupancy detection equipment. Purchasing and installing this 
equipment to compliment the thermostat adds energy savings 
by setting back HVAC operation during occupied and 
unoccupied times. 

Occupancy Operation (Install JP3)

The T180 can be used with PECO S200 series occupancy 
detection equipment. The occupancy and switch inputs are 
designed to connect to the SB200 slave sensor and SE200 door 
switch. 

The Occupancy Sensor is a low-level switch that is open when 
there is occupancy and closed when unoccupied.

The Door Switch is a low-level switch that is open when the 
door is open and closed when the door is closed. This system 
requires both an Occupancy Sensor and a Door Switch. 

Operation From an Occupied Mode

The T180 operates normally and looks for a door close. A door 
close signal initiates occupancy status detection.

If occupancy is detected, the T180 will maintain normal 
HVAC control. It then waits for a door open signal before 
determining occupancy again.

If no occupancy signal is detected within 2 minutes, the T180 
changes to unoccupied mode and controls at setback 
temperature values.

Operation From an Unoccupied Mode

In an Unoccupied State, the T180 sets heating and cooling set 
points to setback values, as determined in the service menu. In 
this mode, the fan is automatically set to cycle with demand. 

The T180 will continually monitor the room for occupancy.

Any occupancy detection, including door open, will set the 
operation to occupied mode.

In either mode, if the door is left open for more than 2 minutes 
the T180 will disable the HVAC system. A one-time ten 
minutes override can be initiated by pressing any thermostat 
keypad. 

Optional detection equipment configurations and operation are 
described below.

SB200-001 Occupancy Sensor

The SB200-001 occupancy sensor (

Figure 11

) serves as an 

occupancy sensor for automatic control of a guest room HVAC 
system. It incorporates an innovative dual delay processor 
which allows the sensor to verify the nature of occupancies, 
and is capable of eliminating unnecessary actuations of the 
HVAC device due to unintentional passages or short time 
occupancies. The sensor may also serve as a slave sensor 
(

Figure 12, page 15

).

The sensor switch is open in occupied mode and closed in 
unoccupied mode. An optional door and/or window switch 
(

Figure 11

) is open when the door/window is open and is 

closed when the door/window is closed.

Note: 

To use this configuration, a jumper must be installed to

JP3 to allow occupancy input.

Note: 

An optional door and/or window switch (

Figure 11

) can 

be added for use with the SB200-001 sensor.

Operation

In an occupied mode, the thermostat operates normally and 
looks for a door open signal. When the door opens, the 
thermostat waits for a door close signal. If the door is open for 
more than two minutes, the thermostat turns the HVAC system 
outputs to OFF. During this two minute period, if any button is 
pressed on the keypad, the time delay is extended to ten 
minutes. The time delay can only be extended once. Once the 
HVAC outputs transition to OFF, a door closure is required to 
re-enable the outputs. When the door closes, the thermostat 
starts a two minute timer and tries to detect occupancy. If the 
timer expires and no occupancy is detected, the thermostat 
transitions to an unoccupied state. If occupancy is detected 
while the timer is running, the thermostat will remain in the 
occupied mode.

In an unoccupied mode, the thermostat sets heating and 
cooling set points to setback values as determined by factory 
or user settings. The fan is automatically set to cycle with 
demand. The thermostat continually monitors the occupancy 
sensor and will enter into occupied mode if occupancy is 
detected.

If the installation is only using a door/window switch, the 
thermostat will disable the HVAC outputs if this output is open 
for longer than two minutes. 

To enable door/window switch only operation, install a jumper 
to JP3 (see 

Installing, Mounting and Wiring the Thermostat‚ 

page 4

) and the occupancy input must be shorted to circuit 

common.
