User Note: The top of this unit will become warm to the touch. This is a
normal operation. Internal heating is employed to continuously convect
air upward through the thermostat, thereby improving room air temperature
measurement. Direct conflict with a downward ceiling fan or system fan air
flow may result in false temperature reading. Locate thermostat to avoid
interference.

delays. If using a motion detector with a door switch, see Entry Door
Switch (Ed) below. Otherwise see Without Entry Door Switch.
Entry Door Switch (Ed): When the door is opened, the thermostat
will go into a temporary occupied mode. If, after a period of time
defined by the Open Door Timer (Odt), no motion is detected the
thermostat will go into unoccupied mode. If Setback Ramping (Sbr)
is disabled, the thermostat will now be controlled by the Economy
Cooling Limit (EC) or the Economy Heating Limit (EH). If Setback
Ramping (Sbr) is enabled, the thermostat will ramp back to the Economy
Cooling Limit (EC) or the Economy Heating Limit (EH). If motion is
detected at any time the thermostat will latch into occupied mode and
remain there until the door is opened again.
Without Door Switch: If, after a period of time defined by the Ramping
Setback Timer (rSt), no motion is detected the thermostat will go into
unoccupied mode. If the Setback Ramping (Sbr) is disabled, the
thermostat will now be controlled by the Economy Cooling Limit (EC)
or the Economy Heating Limit (EH). If Setback Ramping (Sbr) is
enabled, the thermostat will ramp back to the Economy Cooling Limit
(EC) or the Economy Heating Limit (EH). If motion is detected at any
time the thermostat will return to occupied mode.

Pipe Sensor:
A pipe sensor can be used to determine whether there is hot or cold
water in a two pipe system. To activate the pipe sensor, install as
shown and then see programming instructions.
Mount the pipe sensor to the water pipe. The best location is to be as
close to the main pipe as possible and attached before the water valve
connection.
Water
Main Valve
Sensor Wire
Ties
Refer to the programming instructions for selecting the pipe sensor
function, temperature changeover settings, output configurations, purge
frequency and purge time duration. The thermostat will monitor pipe
temperature every 5 seconds. For a valveless systems, select the
2Pn configuration setting since this will bypass the valve purge
functions and provide heating or cooling based on pipe temperature
alone.
The 2PS and 2PE configurations operate with a valve purge function
to prevent incorrect temperature readings from static or standing water
in the pipe. The valve purge operates on a programmed interval
(purge frequency) for a programed duration (purge time duration)
in the event of low activity over an extended period of time.
If the heat or cool call has lasted for more than three minutes, the
pipe temperature heat or cool mode is rechecked to verify proper
operating mode.
