Variable Anger and Venting (of the profane kind) Unfortunately, the Flair belongs to a class of HVAC systems known generically as Variable Air Volume systems, or VAV for short. HVAC systems must control three key parameters in order to provide comfort, namely: Temperature Humidity and "Freshness" (i.e. being able to prevent CO2, odors, etal from building ...

You may not be able to. The programmable thermostats commonly sold are designed for on/off control of a heating and cooling system. The Flair line of thermostats are designed to control a Flair damper that is allowing more or less air into the room. The Open and Closed Signals move the damper in that direction. I believe the Flair is an variable system, ...

simulate this circuit – Schematic created using CircuitLab Figure 1. Most likely original circuit. If you were really fortunate the live feed to the thermostat would have originated at the original switch. You could then have connected it directly to your new controller. Judging by the photos there is only one live wire so this isn't the case. ...

This isn't impossible, but you'll want someone who has done it before You will indeed need to have the gas valve replaced to install a thermostat on this heater -- your existing valve (a Robertshaw 7000SRLC also known as a Robertshaw 710-204) is a hydraulically operated thermostatic valve that has no electrical actuation means, just a safety magnet and ...

This article provides excellent information about maximizing thermal mass: Phase Change Materials (PCMs): There is growing interest in the use of PCMs as a lightweight thermal mass substitute in construction. All materials require a large energy input to change state (i.e. from a solid to a liquid or a liquid to a gas). This energy does not change ...
