This is a unique SPLat Controller that has been specially designed for Heating and Ventilation Control. It uses the same SPLat language that you've come to know and love, complete with multitasking (32 processes for the price of one) and floating point support. What makes it special is its focus on 24VAC compliant inputs and outputs that is the most common voltage used throughout the HVAC industry.

This special focus on 24VAC means this controller can be directly installed in air-conditioner and/or heaters to control all the soleniods directly. In addition, the built-in thermistor inputs provide the most inexpensive method of accurate temperature measurement.

LCD Option

AC24 controller

To minimise cost, the AC24 does not include an HMI.

Be happy though because a full size 20x4 alphanumeric LCD with plenty of buttons can be connected up to miles away from the controller. All you need is a minimum of 2 core shielded wire.

Have a look at either the
UI420 controller or the
HD8 controller.
