Typical Wire Routing

For proper safety all wiring and controllers should be installed separately to avoid accidently contact with one another. Make sure to keep wiring and equipment/controllers six feet from power distribution, motors, etc. If these conditions are not satisfied; irregularities can occur with the system.
With this easy to install and manage product, building developers/managers can deliver a system that exceeds expectations. Comfort control is made possible at a cost savings like no other

Wiring Diagram

The wiring diagram above outlines the basic functions the TSTAT7 thermostat can do for you. With four analog/digital inputs you can plug in occupancy sensors, flow sensors, fan status, freeze protection, power meters and BTU meters just to name a few. There are 2 analog outputs that can be used for modulating valves and modulating dampers. It comes equipped with a RS485 network that can be connected to a controller like a boiler as illustrated above. On the other side we have five relay output capabilities which can be used for air handler units, fan coil units, heat pumps and many other different types of hydronic applications. The TSTAT7 thermostat is compatible with any desire you need and the perfect fit for your next installation.

Operational Functions

Adjustable set-points
The buttons both the up arrow and down arrow allow the consumer to increase or decrease the desired set-point they wish to have. To adjust the set-point on the room sensor can only be done when the occupied symbol is being displayed on the LCD display. To increase the set-point temperature by a degree simply hit the up arrow button. To decrease the set-point temperature by a degree simply hit the down arrow button and continue either step until desired set-point is achieved. After the set-point is increased or decreased the LCD screen will display the current set-point, until the temperature in the room reaches the desired set-point (warmer/cooler) of the occupant.

There are six buttons that operate the Tstat7:
