The Heat6 has six channel buttons with status LEDs, an All-on and an All-off button, a Man./Auto. button with LED, and a Programming button with LED, all on the front of the device.

⚫	Off	Valve closed
🟢	Blinking, 1 s on and 1 s off	Short circuit, overload or undervoltage on that output

Manual / Auto

Press and hold the Man./Auto. button for one second to switch between manual and automatic operation. The LED is on in manual mode and off in automatic mode. The device can also return to automatic after 10 to 6000 seconds without a button press.

Manual operation has to be enabled in ETS before the buttons work.

Channel buttons

Each channel button opens and closes the valve on that channel. All-on opens all six valves, All-off closes them.

TIP

Manual and forced operation take priority over a valve purge and cancel it. See Valve Outputs.
