Product FAQ:

Q: What type of heating and cooling systems is the Lux TX9600TS compatible with?
A: The Lux TX9600TS is compatible with most 24-volt heating and A/C systems, two stage heating/one stage cooling. However, it is not compatible with electric baseboard heat (120 or 240 volt) and systems with 2-cooling stages.

Q: Does the Lux TX9600TS have a lockout feature to prevent unauthorized users from changing the settings?
A: Yes, the Lux TX9600TS has a programmable touch pad lockout feature that allows users to set a four-digit code to lock the screen.

Q: Can the Lux TX9600TS be used with batteries only if there is no "C" common wire?
A: Yes, the Lux TX9600TS can be used with batteries only if there is no "C" common wire. The batteries will last for approximately one year.

Q: Will the Lux TX9600TS work with a two-stage 96 efficient gas furnace?
A: Yes, the Lux TX9600TS will operate a two-stage gas heat furnace. The thermostat should have a W1 & W2 wires going to it if it is doing the staging. If not, then there will be one W1 wire and the furnace will do the staging.

Q: How low can the temperature be set in heat mode with a gas furnace?
A: The temperature can be set as low as 45 degrees Fahrenheit in heat mode with a gas furnace.

Q: What are the dimensions of the Lux TX9600TS?
A: The dimensions of the Lux TX9600TS are 5.38 x 1.13 x 3.38 inches.

Q: Does the filter replacement warning use run time or just the date?
A: The filter replacement warning uses run time rather than just the date. The default value of 720 hours is normally used for a 90-day filter.

Q: Can the Lux TX9600TS be set to turn on every two hours and then turn on after one hour of running?
A: No, the Lux TX9600TS is programmed by clock times rather than number of hours. It is limited to four different time/temperature settings.

Q: How does the Lux TX9600TS perform when powered by batteries versus 24 V AC?
A: The Lux TX9600TS performs well with batteries alone but has poor performance with 24 V AC. When powered by AC, noticeable temperature swings and prolonged cycle durations occur even though the thermostat’s temperature swing is set at its minimum of +/-0.25°F. The disadvantage of powering the thermostat by batteries alone is that you must remember to replace the batteries when they get weak and make sure to have fresh batteries on hand.
