Example Application
Sample Mechanical Diagram
The sample mechanical diagram illustrates a typical HVAC system setup. It shows an optional outdoor sensor connected to a thermostat display. The thermostat display communicates with an HVAC Interface Module. This module is wired to a furnace, an air conditioner (DX unit), a humidifier, and a heat recovery ventilator. Additionally, an optional Watts FloodSafe Water Detector Shutoff is shown connected to a hot water tank and the HVAC Interface Module.
Sample Electrical Diagram
The sample electrical diagram details the wiring connections between the thermostat display, HVAC Interface Module, and various HVAC components. The thermostat display connects to the HVAC Interface Module via terminals labeled 'To T-Stat', 'AWAY', 'SEN', 'COM', 'S1', 'S2', 'S3', 'Rh', '3V3', and 'Water Detect'. The HVAC Interface Module itself has terminals for power ('R', 'C') and connections for HVAC components: 'Rh1', 'W1', 'Rh2', 'W2', 'Rc', 'Y1', 'Y2', 'G', 'ACC1', 'ACC2/O/B'. The diagram also shows connections for a Heat Recovery Ventilator (terminals R, G, HUM), a Humidifier (terminal HUM), a Furnace and Air Conditioner (terminals R, C, W1, W2, Y1, Y2, G, DX), and the Optional Watts FloodSafe Water Detector (terminal Water Detect).
