Single and Multistage Programmable and Non-programmable Thermostat
The model KT600 is a digital display single or multistage 7-day programmable or non-programmable PI thermostat (ºF or ºC). It is used with AHU control and heat pump for both heating and cooling applicatuions. The KT600 has both system and fan switching with internal or remote senor capabilities. Five buttons control a simple menu for setup of over 20 configurable parameters. Other control features are listed below.
