EEC Control

EEC Settings are used to configure Energy Efficient Control (EEC), 2nd Stage Differential, and

Auxiliary Heat Differential. Not all of these features apply to all thermostat configurations. Only the

features that apply to the current configuration (based on the System Type and Stage Settings) of the

thermostat are available when this menu is selected. This thermostat is equipped with EEC that

continually monitors the performance of the HVAC system and uses Stage 2 (heat or cool) and Stage

3 (auxiliary heat) only when necessary. If the thermostat determines that Stage 1 is able to heat or cool

at a rate of 5° per hour or better, Stage 2 will not be used. If Stage 1 is unable to heat or cool at this

rate, the thermostat will use Stage 2 as needed. Under these conditions, Stage 1 will run continuously

and Stage 2 will cycle on and off as needed. In extremely cold conditions, the auxiliary heating will be

used when Stage 1 and/or Stage 2 is not heating at a sufficient rate.

EEC: configures Energy Efficient Control. EEC continually monitors the performance of the HVAC system

and uses a PID algorithm and auto balance routine to achieve comfort while saving energy. A setting of 0

will disable EEC. When EEC is disabled, the EER56100 thermostat will attempt to maintain the

temperature within 0.5 °F of the setpoint. A lower setting of 2–3 can be used for slow reacting sources (e.g.,

radiant heat) and higher setting of 7–8 for fast reacting sources (e.g., forced air). The default setting is 5.

2nd Stage Differential: determines how far from the setpoint the temperature must be before the

second stage turns on.

Auxiliary Heat Differential: determines how far from the setpoint the temperature must be before the

auxiliary heat turns on. This is only available for heat pump systems.

Start Delay (Minutes): sets the minimum amount of time the heating system must run before the

Auxiliary Heat Stage is used. To use start delay, EEC must be enabled and Hold must be off.
