Introduction
The T1100 digital thermostats are networkable, microprocessor-based
thermostats designed for zoning applications. Proportional and integral (PI)
control loops, working in conjunction with fully customizable outputs (1 analog / 1
digital) deliver accurate yet flexible control strategies. An auxiliary analog input is
available for zone temperature averaging or as a radiant floor slab temperature
input. Configuration, performed via a capacitive circular touch pad, is made easy
through an intuitive menu system displayed on a backlit graphic LCD screen.
Installation
1. Open casing to remove back cover by
pushing on the tab located underneath the
thermostat. (Figure 1)
2. Pull wire(s) through central hole of back
cover.
3. Screw in the back cover to the wall.
4. Connect wires:
Pull out the screw terminal blocks.
Remove 1 cm insulation from the end of
each wire.
Connect the wires to the terminal
blocks: see Figure 2 for pin
identification. Typical wiring examples
can be found below.
Reinstall terminal blocks.
5. Reconnect top cover
Important: Do not install the thermostat under
the following conditions:
xAny location exposed to direct sunlight
xOn an outside wall
xNear an air discharge grill
xIn a location where vertical air circulation
is restricted
xNear a dimmer switch

Power source
The T1100 is powered by a 24 VAC
power source connected using the
"COM" pin and the "24 AC" pin (see

The T1100 can work autonomously
or networked. When networked, it
will communicate in real-time with
other ProLon controllers. The T1100
uses the Modbus RTU protocol over
RS485. A unique network address
must be assigned to each device on
the network. For the T1100, this can
be done through the menu system.
The network connections are made
using the “NETA” (+) and “NETB” (-)
pins (
Figure 4: Network Connection
Figure 4). Bias and terminating
resistors can be activated or
deactivated using jumpers on the
back of the PCB (see Figure 5). Bias
and terminating resistors are used to
improve signal quality in an RS485
network. For more information
regarding application of network
resistors or shielding, see the
ProLon Network Guide.

Auxiliary Analog Input
The T1100 has an auxiliary analog
input which can be used to connect
another thermistor. The T1100 can
be configured to use this alternate
temperature reading for a variety of
functions, including temperature
averaging or radiant floor slab
temperature. The alternate
thermistor (10KΩtype 3) can be
connected to the auxiliary input using
the “AUX IN” and “COM” pins (see

Outputs Specifications
The T1100 series thermostats contain a fully customizable Triac output and a 0-
10VDC output to drive components. An integrated resettable fuse protects both
outputs of the T1100 against current surges and short circuits. This protection will
cut the current to the output as soon as an overload condition is detected. The
fuse is round and yellow-colored which, upon a short circuit condition, will heat
up and change to orange. When the faulty wiring or circuit is fixed, the fuse will
automatically reset and allow current to flow through the output again.

Operation
The T1100 is controlled using the
circular touch pad on the bottom half of
the thermostat. The touch pad uses
capacitive sensing technology to detect
finger proximity. There are no moving
parts to push or rotate. The T1100 is
controlled using simple scrolling, tapping
or holding motions, performed around
the circle of the touch pad. The center of
the circle is unused.

Section Description Min Max Default Units
1.1) Temp Unit Lets you select between Celsius or
Fahrenheit temperature display. --Celsius-
- - Internal -
1.2) Temp
Source Lets you decide how the zone temperature is determined:
Internal
•(Only the onboard thermistor
is used to calculate temperature)
External
•(The temperature reading is
obtained from an external thermistor
connected to the auxiliary input)
Average
•(The temperature reading is
obtained from an average of both the
internal thermistors reading and the
reading obtained from the external
thermistor connected to the auxiliary
input. )
NOTE: When an output is set to control a
radiant floor, the external input is
automatically dedicated to slab
temperature sensing.
