G. Once the correct temperature value has been selected, not pressing any buttons for
15-seconds will allow the controller to save the selection and return to the normal operating
mode. Pressing the [POOL/SPA] key will also save the selection and step to the next menu
parameter: [dBS] (Dead Band for Spa).
6. Spa Dead Band Differential [dBS]:
In the heating mode, the dead band differential determines the number of degrees the water
temperature must fall below the set point before the thermostat closes. In the cooling mode, the
dead band differential determines the number of degrees the water temperature must rise above
the set point before the thermostat closes. When in the auto-changeover mode, the dead band
differential operates in the same manner as described above for the heating and the cooling modes.
However, in all modes, the thermostat will open when the set point is reached independent of the
direction the water temperature is changing. The factory spa dead band differential is set to 1
o
F. It
is strongly recommended the factory default of 1
o
F remain; however, if for some reason the dead
band requires adjustment, follow the steps outlined below:
A. Follow the steps 1, A through 1, D to enter the service menu. Once [dEL] is displayed, press
the [POOL/SPA] key until the display shows [dBS] (Spa Dead Band Differential).
B. With the service menu parameter [dBS] displayed, pressing either the [UP] or [DOWN]
arrow keys, once, will display the current setting. Using the [UP] or [DOWN] arrows keys will
increase or decrease the value respectively. The differential is adjustable in 1
o
increments
from 1 to 5-degrees.
C. Once the desired dead band value has been selected, not pressing any buttons for
15-seconds will allow the controller to save the selection and return to the normal operating
mode. Pressing the {POOL/SPA] key will also save the selection and step to the next menu
parameter: [dBP] (Dead Band Pool).
7. Pool Dead Band Differential [dBP]:
In the heating mode, the dead band differential determines the number of degrees the water
temperature must fall below the set point before the thermostat closes. In the cooling mode, the
dead band differential determines the number of degrees the water temperature must rise above
the set point before the thermostat closes. When in the auto-changeover mode, the dead band
differential operates in the same manner as described above for the heating and the cooling modes.
However, in all modes, the thermostat will open when the set point is reached independent of the
direction the water temperature is changing. The factory pool dead band differential is set to 1
o
F. It
is strongly recommended the factory default of 1
o
F remain; however, if for some reason the dead
band requires adjustment, follow the steps outlined below:
A. Follow the steps 1, A through 1, D to enter the service menu. Once [dEL] is displayed, press
the [POOL/SPA] key until the display shows [dBP] (Pool Dead Band Differential).
B. With the service menu parameter [dBP] displayed, pressing either the [UP] or [DOWN]
arrow keys, once, will display the current setting. Using the [UP] or [DOWN] arrows keys will
increase or decrease the value respectively. The differential is adjustable in 1
