2.3.1.7. EXIT

Press the

button (or highlight EXIT and press the

button) to exit the Mod menu and return to the Outputs

menu.

If you have a second modulating output to configure, go to

“2.3.1. Setting up the Modulating Outputs” on page 21.

If you are finished setting up the modulating outputs,

continue with “2.3.2. NBR OF RELAYS”.

Fig. 56. Setup - Outputs - Number of Relays.

2.3.2. NBR OF RELAYS

From the Outputs menu, use the

and

but-

tons to highlight # RELAYS.

Press the

button to display the number of relays.

Use the

and

buttons to display the number

from 1 to 4 depending on the model. (See notes

below.)

Press the

button to accept the value and display

the Outputs menu.

NOTES:

The T775A/B/M models have the following

outputs available:

T775A20191 relay output

T775B2016up to 2 relay outputs

T775B2024up to 4 relay outputs

T775B2032up to 2 relay outputs

T775B2040up to 4 relay outputs

T775M2006no relay outputs

T775M2014up to 4 relay outputs

The number of relay outputs entered here

determines how many relays display on the

home screen.
