It meets State Energy Code requirements by using automatic controls that only activate emergency electric heat if the heat pump cannot maintain the desired temperature.\u003c\/p\u003e\u003cp\u003eThe standard kit includes a 7-day programmable thermostat, a 120\/240V 20A electric heat relay, and a 24V HVAC relay.\u003c\/p\u003e\u003cp\u003eOptional wireless RF sensors can detect when someone is in the room or if a door or window is left open and adjust the temperature automatically. An outdoor sensor can be added to limit electric heat use when the heat pump can meet demand, and enable it when outdoor temperatures fall below the heat pump’s effective range. Plus, multiple rooms can connect to a wireless master switch, letting you adjust the whole building with one button.\u003c\/p\u003e\u003cb\u003eFeatures\u003c\/b\u003e\u003cul class=\"kel-product-feature-list\"\u003e\n\u003cli\u003eKit Includes KRFTP-B RF 24V RF Thermostat, KRFLR-120\/240 20A RF Heating Relay, KRFR-24V 24V RF HVAC Relay\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eWireless Two-way RF Communication - 915 MHz\u003c\/li\u003e\n\u003cli\u003e24V Heat pump or HVAC system, control (Heating Cooling) with Touch Screen display.\u003c\/li\u003e\n\u003cli\u003e7-day programmable schedule\u003c\/li\u003e\n\u003cli\u003eModes: Auto\/Cool\/Fan Only\/Off\/Heat with Auto Emergency Heat\/ Manual E.
