I want to use a Jace with an expansion module to open a valve for a set period determined by some sort of numeric input from a keypad device or a touch screen. Has anyone done this before without using one of the communication protocols? I only need to compare the time that the valve is open to the time set at the input. The logic for this is fairly simple but I am not sure what if anything I can use to inout the numeric (time) value to one of the universal inputs on the expansion module.
I am aware that I can use a Auto-Matrix touch screen or a Distech EC-Display to accomplish this but I am trying to avoid having to purchase the drivers etc. to make this happen.
I chose the Jace to do this because I also have to send e-mail notifications and dry contact alarm outputs based on the operation.
