Description
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 exible control strategies. An auxiliary analog input is available for zone temperature averaging or
as a radiant oor slab temperature input. Conguration, performed via a capacitive circular touch pad, is made easy
through an intuitive menu system displayed on a backlit graphic LCD screen.

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 identication. Typical wiring examples
can be found below.
•Reinstall terminal blocks.
5. Reconnect top cover
Installation
Figure 2 - Terminal Block Pinout
IMPORTANT: Do not install the thermostat under the following conditions:
•Any location exposed to direct sunlight
•On an outside wall
•Near an air discharge grill
•In a location where vertical air circulation is restricted
•Near a dimmer switch

Power Source
Network Setup
The T1100 is powered by a 24 VAC power source connected using the "COM" pin and the "24 VAC" pin. The common for
the power source is shared by the auxiliary analog input and the analog output.

NL
120VAC24VAC
24VAC
COM
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 us-
ing the “NET A” and “NET B” pins (Figure 4). Bias and terminating resistors can be activated or deactivated using jumpers
on the back of the PCB (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 congured
to use this alternate temperature reading for a variety of functions, including temperature averaging, radiant oor slab
temperature or discharge air control. The alternate thermistor (10KΩ type 3) can be connected to the auxiliary input
using the “AUX IN” and “COM” pins.

REV. 7.3.0 / PL-HRDW-T1100-F-EN
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 xed, the
fuse will automatically reset and allow current to ow through the output again.
Typical Wiring of the Digital Output
The T1100 opens and closes a triac contact to allow an external source to power the load.
Typical Wiring of the Analog Output
The T1100 provides the control signal to the load, which is powered externally or from the same power source as the
T110 0 .

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 nger 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.
Hint Display
At the bottom of the screen, a circle representing the touch pad is displayed, with hints on how to navigate and modify
settings, as well as providing feedback as you manipulate the touch pad. Hints are context-sensitive and will only display
where logical.
