Multistage Seven-Day Programmable Thermostat

Order Now!

The KT7351 is a single or multistage seven-day programmable thermostat ( ℉ or ℃ ) for use with AHU control for both heating and cooling applications. It is designed for low voltage power and switching to control within 1℉ (1.8℃) using Proportional plus Integral (PI) algorithms, and it includes adjustable delays to prevent equipment short cycling. The KT7351 has both system and fan switching with an internal sensor or remote sensor capabilities. It also has a number of energy-saving programs such as a seven-day clock with two occupied and unoccupied periods per day, optimal start, single-button continuous unoccupied, and adjustable occupied override. The cover has an easy-to-read digital display for temperature, time, system status, and fan status and 16 dedicated buttons for day-to-day control necessities. The temperature display can be disabled or offset to enhance occupant perceptions. Other control features are listed below.

This unit was pretty ideal for our application. The only drawbacks are:
1) that you cannot set different setback temperatures for your daily unoccupied periods, i.e.: setback midday to 65 but at night setback to 60.
2) there is no way to adjust the hysteresis of the heating and cooling stages. We used first stage to turn on some high bay fans, second stage for furnaces, and third stage for alarm, but it would be nice to be able to adjust the on points of each stage.

Pros: Good value

Yes, I recommend this product.
