A solid-state guardian cf your heating needs--with no moving The Comfort Computer has several advantages over conventional thermostat or zone control mechanisms including outdoor temperature sensors. It is not directly dependent on mdoor-outdoor temperature variance, so you need not worry about finping a special location for it--or concern yourself with shade effects, wind change or those days when the sun cannot make up its mind whether to shine or not. And this electronic marvel really pays off when you are entertaining. Remember how hot it gets when the bridge club is over, or those 15 or 20 kids come for the Scout meeting? That was because your conventional zone valve delivers one characteristic water temperature regardless of the number of zones calling for heat or the duration of the call. With the Comfort Computer, you can relax. The water temperature delivered to any zone or zones is modulated to balance the integrated demand of all zones. The water temperatures are constantly chocked--electronically--so the slightest variance can be measured. As the crowd fills the room, the demand becomes less and the Comfort Computer begins tapering off on the heat supply. Meanwhile, the rest of your house is also being monitored, too. Bedrooms are still pleasantly cool, the living room or playroom is still "just the way you like it." And most importantly, you are free to enjoy your home--no readjusting thermostats, no need to worry about the rest of the house getting too cold and no need to open windows and risk colds! You II even find unsightly wall-streaking is reduced, too, for modulated water temperatures avoid those peak temperatures contributing to that nuisance. IT'S THE SPACE-AGE! And you can be in if with AMERICAN-STANDARD! The Comfort Computer it ovoiiobit factory-mounted with the two, three and four-rone valve packages currently offered.
