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 1oF. It is strongly recommended the factory default of 1oF 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 1o 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 1oF. It is strongly recommended the factory default of 1oF 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 1o increments from 1 to 5 degrees.
