TS-2 Thermostat Stations are designed to replace a thermostat connected to a standard HVAC unit. The TS-2 can be used to control most HVAC systems including heat pump systems and multi-stage HVAC systems. The TS-2 connects to the HVAC system using the same low voltage thermostat wire, and has the standard color-coded wiring as most thermostats. The Hydro-x allows for independent Day and Night settings for each of the (4) TS modules, so a single Hydro-X system can control multiple HVAC systems. The TS-2 also features an adjustable time delay for each HVAC system that is activated. This minimizes sudden starts (inrush current) and allows for safe control of up to 4 HVAC systems.
