TomorrowHouse Systems International Inc.

WHY THREE HVAC CONTROLLERS?

The market scope of TomorrowHouse is a broad spectrum in that residential and commercial HVAC systems can be accommodated. Heating and Cooling costs can vary from a simple structure in a temperate climate zone where $100.00 per month is experienced for a residential unit to thousands of dollars for commercial spaces. Obviously, the higher the energy costs, the more money can be justified for the purchase of the HVAC Controllers that improve overall system efficiency. TH-1A and TH-1H is more cost effective for residential use while the commercial market range would use the TH-2A and TH-2H or TH-3.

ENERGY MANAGEMENT SYSTEMS

All three TomorrowHouse Controllers are compatible with energy management systems such as Honeywell, Johnson Controls, Novar, etc. Also, all three controllers are compatible with OEM HVAC system controls. The TomorrowHouse Controllers are "stand alone" and perform dynamic demand sensing that is backed by an at least 20% energy savings guarantee. This dynamic functional feature enhances conservation and is not available from any other source or designed into any other system.

TomorrowHouse I (Models TH-1H and TH-1A)

TomorrowHouse Sensors, TH-1H and TH-1A, are updated versions of patented Temper-Sensor Models DCH 020 and DCA 005 respectively. The TH-1H is used for heating system control and the TH-1A is used for air conditioning system control.

The TH-1H and TH-1A are UL approved, and utilize a proven, mature technology; the primary control component of both sensors is a bimetal switch that is activated based on sensed demand (heat loss to climate conditions) of a controlled space. During installation, the sensor(s) is/are mounted onto the supply plenum, and calibrated to the specific HVAC control circuit and space. This alignment more effectively delivers energy to the controlled space improving comfort, lowering average temperature and as such saves energy.

The TH-1H is calibrated to "open" the heat input control circuit (gas valve, oil valve, etc.) after the heated air temperature has increased to a point that approaches thermal saturation (full-on). The TH-1A is calibrated to "open" the air conditioning compressor control circuit after the cooled air temperature has decreased to a point that approaches thermal saturation in a similar way. Operationally, even though the thermostat in tandem is at times calling for more cooling or heating based on the local temperature at the thermostat, the Thermostat-Plus ad-on device(s) regulate on the sensed demand until ultimately the set point is reached.

TomorrowHouse improvements to the Temper-Sensor design include:

TomorrowHouse Sensors, TH-2H and TH-2A, are electronic versions of TH-1H and TH-1A respectively. The TH-2H is used for heating system control and the TH-2A is used for air conditioning system control.

The TomorrowHouse II design replaces the bimetal thermostat switch with a micro-controller PC board, a solid-state temperature sensor and an integral control relay. The controller program is nonvolatile so additional software is not required, and electrical power interruptions do not cause operational problems. A unique design feature of the control board is it's ability to function as a heating OR air conditioning controller via a select switch. Utilization of a single control board will reduce manufacturing cost.

The TomorrowHouse (series 2) controllers are mounted onto the supply plenum; they are calibrated to "open" the HVAC control circuit when the system reaches thermal saturation and are calibrated to "close" the circuit at a designated temperature. Unlike the TomorrowHouse I series where the "open/close" temperature differential is limited and fixed by the characteristics of a bi-metal thermostat, the TH-2 series "open/close" differential is fully configurable for any extreme.

The TH-2H is calibrated to "open" the heat input control circuit (gas valve, oil valve, etc.) after the heated air temperature has increased to a point that approaches thermal saturation. The TH-2A is calibrated to "open" the air conditioning compressor control circuit after the cooled air temperature has decreased to a point that approaches thermal saturation.

TomorrowHouse (series 3) is an auto-calibrating, dual mode version of TH-2H and TH-2A. The TH-3 is used for heating system and/or air conditioning system control.

The TomorrowHouse III design utilizes a micro-controller PC board, a solid-state temperature sensor and integral control relays. The controller program is nonvolatile additional software is not required and electrical power interruptions do not cause operational problems.

The TomorrowHouse (series 3) controller is mounted onto the supply plenum; it is auto-calibrating, so it does not require manual calibration to "open" the HVAC control circuit at thermal saturation. The TH-3 continuously samples the supply air temperature. When thermal saturation is determined, the controller "opens" the control circuit and when the air temperature crosses the "reset" temperature threshold, the control circuit is again "closed".

TomorrowHouse (series 3) incorporates key features of TomorrowHouse (series 2) and also includes additional major features:
