CONFIGURATION MODE
The configuration mode is used to set the RAK148F2 and
RAK164F2 to match the heating/cooling system. These
thermostats function with up to 2-stage heat pump systems
(RAK148F2 only).
To configure the RAK148F2 and RAK164F2, perform the
following steps:
Note: Operation being set will blink in the display.
1. Slide the Function switch to the OFF position.
2. Remove the thermostat’s front cover.
3. To enter the configuration mode, simultaneously hold

- Press the LEFT button to return to the previous screen.
NOTE: To exit configuration mode at any time, slide the
Function switch to Heat or Cool.
Configuration Mode Settings
The setup screens for Configuration Mode are as follows:
1. Temperature Scale (F or C)—Choose Fahrenheit or
Celsius.
Press the
< or > button
to select.
Press the RIGHT button to advance to
the next screen.
NOTE: Default factory setting is Fahrenheit.
2. Temperature Differential—Stage 1—
