Honeywell TL7235A1003 Line Volt Pro Non-Programmable Digital Thermostat with Electronic Temperature Control, 240-Volt

Replaced my previous one that was installed with the infloor heating. Works perfectly.

Dec 12, 2011 Followup Review...Units in Operation I have been using two of these for about a month now and the temperature variation between them in steady state still is about a degree. However, now I find that when the units startup their respective electric heaters the temperature variation in steady state becomes greater between them. Also, I am a little dissapointed that the these units shut off power to the electric heaters before the set temperature is reached on the display. I am not sure why or how they do that, seems to me if I set it for 70 degrees then until the thermostat registers 70 degrees on the external green display that is when it should turn off, and not before. Rating these on a scale from 1-5 I am now giving these a rating of 2.5, they work a little better than an analog dial and look nicer but shutting down before reaching set temperature is not acceptable. Previous Review... The Honeywell TL7235A1003, LineVoltPRO is a nice looking unit, easy to install and functions well for my basement electric heat application. There is a single 1 degree F of variation between the two units that I ordered but that is to be expected. These are much more accurate than the dial analog type I had installed before and with these I have a general idea within a few degrees of the actual room temperature. I used three separate digital temperature gauges placed right next to the thermostat to verify the temperature reading of the thermostat unit and the t-stat is within a degree or two of the average of the three gauges. So with this unit I feel confident that what the t-stat measures is what is actually the temperature in the room. I will order more of this model if I need them in the future from this vendor. The vendor quickly sent the new packaged units.

This product was great quality and easy to install. It was easy to program and has has a blacklight.

Excellent

Replaced old school Honeywell rotary thermostats (new ones in white) for baseboard heaters. Temperature control wasn't precise on those and they wore out over time in my experience. Just because you set it at 65 or 70 didn't mean the actual room was going to be 65 or 70. It was an aged mechanical design. Enter TL7235A1003. Installation was simple. Disconnect red and black from old thermostat and reconnect to this. Only word of caution. The footprint on this is a tad smaller than old rotary thermostat. A little paint tuch up may be necessary. Appearance is modern and sleek. Backlight is nice. Real time temperature is accurate and precise. Best part is once temperature begins to reach desired setting, I believe the thermostat backs off and shuts down power to baseboard heater. Heater continues to provide residual heat. Say you set it at 68, at about 65-66 power is reduced or shut down and temperature gradually rises to 68. Temperature falls to 66-67 and it gives it a little more juice. The heat on indicator has three bars. It reduces to two and then one when this setting is in action. Good price too. Big box stores do not stock item, online only. Programmable thermostat appeared to be a PITA IMO for a few bucks more. Went this route. Purchase again? YES
