AC1-27
DIN rail thermostat
The AC1-27 is a universal controller with two independent outputs.
You can select the operating mode (heating/cooling) for each channel in the menu, as well as whether you wish to control the channel with hysteresis or PID control!
For easy configuration, it is equipped with a guided parameter programming system, so that only the parameters required for the specifically selected application are displayed.
This makes programming the controller faster and more efficient.
The two setpoints can be adjusted to requirements instantly using the L1 and L2 keys.
Naturally, the AC1-27 also features a standby (I/O) key and an info menu.
