THZ-100 Thermostat Installation
Introduction
The THZ-100 Thermostat from URC is a stand-alone thermostat coupled with the ability, when used with a
Total Control system, to be controlled from any user interface in the system.
Some of the advanced, and unique features found on the THZ-100 are:
Optional Wired Sensor
Easily add an additional sensor to the thermostat by purchasing the optional wired sensor. With the abil-
ity to temperature average between the sensor and the main unit, or simply take the place of the main
unit's on-board sensor, you can increase both efficiency and accuracy of temperature readings.
Intelligent Comfort Recovery
Every good thermostat has the ability to set heating and cooling schedules, but if you wake up at 7:30am,
setting your heat to come on at 7:30am means waking up to an uncomfortable home while your system
reaches your desired temperature. With Intelligent Comfort Recovery, the THZ-100 monitors the current
temperature of your home and determines the amount of time it will take to reach your desired tempera-
ture at the desired time. Then, it slowly and more efficiently heats or cools to the new set point.
Security Code
Perfect for most commercial uses, and even for some homes where people have the need to ensure that
only authorized people should have access to the THZ-100. Easily program your new thermostat with a 4-
digit security code to make sure that only people with the code can access the thermostat.
Total Control Peripheral
Perhaps the best benefit is the THZ-100's complete integration into a Total Control home system. When
used with URC's Total Control system, the thermostat control can be accessed from any of the system's
interfaces (dependent upon the system programmer). With the ability to control all of the THZ-100s in
the home, it is also easy to incorporate heat/cool set points into various Automation Activities. Although
the possibilities are endless, imagine a Goodnight button that would turn off your theater, turn off all the
lights and bring the THZ-100 to the chosen set point!
