the current heat set point does not fall out-
side the SH limits
SC Cool Mode Set Point Two or three digit integer: 42 - 90 for °F;
6 - 33 for °C
SC++ Increment cool set point Integer value which when added to the cur-
rent cool set point does not fall outside the
SC limits
SC-- Decrement cool set point Integer value which when deducted from
the current cool set point does not fall out-
side the SC limits
S Current Mode Set Point Two or three digit integer (see next two
commands)
SP++ Increment current mode set point Integer value which when added to the cur-
rent mode set point does not fall outside
the SH and SC limits
SP-- Decrement active set point Integer value which when deducted from
the current mode set point does not fall out-
side the SH and SC limits
