Installation

Introduction

Congratulations on choosing the SuperSTAT™ modulating thermostat! The SuperSTAT series of controllers are feature
rich, multifunction devices providing extensive controls across a wide range of HVAC applications.
This manual applies to Model SZ1041. It includes all the information necessary to install and wire your SuperSTAT. It
includes a breakdown of the input and output wiring for each model and each type of connection.
After installing your SuperSTAT, refer to the
device, the communications network and other devices connected to this controller.
If you have any questions regarding your SuperSTAT, do not hesitate to contact TCS Technical Support at 800.288.9383,
ext. 2. Our Technical Support Department hours are Monday – Friday, 7:00 a.m. to 7:00 p.m. (CST).

Opening the SuperSTAT

The SuperSTAT consists of a base containing wiring terminal blocks and relays, and a front cover containing the keypad
and all other circuitry.

Mounting the SuperSTAT

Mount the base of your SuperSTAT on a vertical wall using two #6 sheet metal screws, either over a horizontally mounted
2" x 4" junction box or a 4" x 4" junction box, or directly to the wall. For best results, select an interior wall that represents
a normal room environment, at a height of about 48" from the floor. Mount the unit in a location which is accessible for
adjusting settings.
For best temperature measurement accuracy, avoid areas that are exposed to direct sunlight, unusual heating or cooling
sources, open doors and windows, unventilated locations, and hot or cold air from diffusers. If you are using a remote
room sensor, mount it in the same manner.

Powering the SuperSTAT

The SuperSTAT is powered from 24 VAC +15%/–5% and draws up to 10VA. If wiring for communications, you must use
dedicated power (transformer) to the unit. Several TCS controllers may be powered from the same transformer, provided
the transformer has sufficient power and you maintain proper polarity. While the SuperSTAT may be powered from the
HVAC unit controller, using a dedicated power source will avoid any potential ground loop issues between equipment
transformers.
When the SuperSTAT is used as a stand-alone thermostat without communications, the equipment transformer may be
used to power it. To do this, install a jumper between the "R" (Packaged Unit Terminations) and "+24" (Power) terminals.
The "–24" (Power) terminal must then be connected to the common side of the equipment transformer.
