COMPATIBLE SYSTEMS

Smart Thermostat Premium works with most centralized residential heating and cooling systems.

• Heating: Up to 2 stages
• Cooling: Up to 2 stages
• Heat pumps: Air, Water, and Geothermal with up to 2 stages, and 2 stages of AUX heat. Accessories: Dehumidifier, humidifier, or ventilation device.
• Fan coil units: 2- and 4-Pipe with up to 3 fan speeds. Pipe sensors supported.
• Packaged Terminal Air Conditioners (PTAC): Up to 3 fan speeds

IMPORTANT — TURN OFF THE POWER
Power off the HVAC system with the master switch or circuit breaker box.
WARNING! ecobee Smart Thermostat Premium is designed for 24VAC with a 2A maximum current. Do not connect it to line (high) voltage or millivolt systems.

TERMINAL DESCRIPTIONS

• G Fan
• Rc Cool transformer
• Rh Heat transformer
• O/B Heat pump reversing valve
• Y1, Y2 Used for 1-2 stages of conventional A/C or 1-2 stages of heat pump compressor
• W1, W2 Used for 1-2 stages of conventional heat or 1-2 stages of auxiliary heat with heat pump
• C 24VAC common

CONVENTIONAL HEATING AND COOLING
(UP TO 2 STAGES EACH)

CONVENTIONAL HEATING AND COOLING
(WITH PEK)

NOTES:

1. When using a PEK with a heat pump system, the O/B terminal is wired directly to the thermostat.
2. The PEK is not compatible with dual transformer or fan coil units.

HEAT PUMP (AIR OR GEOTHERMAL)
WITH AUXILIARY HEAT

NOTE: Heat pumps use an internet-based weather feed and do not require outdoor temp sensor and/or a dual-fuel kit.

PACKAGED TERMINAL AIR CONDITIONER
(PTAC) WITH MULTISPEED FAN

NOTE: G1, G2, G3 may also be labeled as GL, GM, GH

1-WIRE ACCESSORY

NOTE: Self-powered 24V accessories can be controlled using the ACC+ and ACC− terminals.

2-PIPE FAN COIL UNIT WITH AUX HEAT
(PIPE SENSORS OPTIONAL)

NOTE: G1, G2, G3 may also be labeled as GL, GM, GH

4-PIPE FAN COIL UNIT

NOTE: G1, G2, G3 may also be labeled as GL, GM, GH

Cool Differential Temperature	The minimum temperature differential before engaging cooling.	Auto
Cool Dissipation Time	The amount of time the fan will continue to run once the cooling cycle is completed.	Auto
Compressor Reverse Staging	When enabled, second stage compressor will be engaged if the current temperature is greater than the value designated in the Compressor Stage 2 Temperature Delta setting.	Off
Compressor Stage 2 Temperature Delta	The minimum number of degrees from the current temperature vs. set point before engaging the second stage of the compressor.	Auto
Compressor Stage 1 Max Runtime	The maximum number of minutes running stage 1 before engaging the second stage of the compressor.	Auto
Heat Reverse Staging	When enabled, second stage heat will be engaged if the current temperature is greater than the value designated in the Heat Stage 2 Temp Delta setting.	Off
Heat Stage 2 Temp Delta	The minimum number of degrees from desired setpoint before engaging the 2nd stage of heat.	Auto
Heat Stage 1 Max Runtime	The maximum number of minutes running stage 1 before engaging the second stage heating.	Auto
