AC2-5
Universal Thermostat
The AC2-5 is a universal controller with two independent outputs. You can
select the operating mode (heating/cooling) for each channel in the menu, and choose whether
to control the channel via hysteresis or PID control! For
easy configuration, it features a guided parameter programming system
which ensures only the parameters required
for the specific application are displayed. This makes programming
the controller faster and more efficient. The AC2-5 also
includes a standby (X) button and an info menu.
