• Check if the 'Safety is Activated' error is displayed. High limit (Heating)
or Low limit (Cooling) may have reached. Check the air-conditioner to
see if it is operating normally. AirTouch system will resume to
operational after the supply air temperature is within safety range.
• *Check if Supply air sensor is plugged in the mainboard and High Limit
& Low Limit is enabled. If the sensor is not plugged in, plug the
sensor and the system will be operational after a minute. If the sensor
is not required, disable High limit and Low limit from touchpad and
system will return to operational in a minute.
• *Check if LEDs on the main module light up for relevant zones when
the zone dampers are being turned On/Off. If Green/Red LEDs are not
activated for the respective zone, the main module may be faulty, replace it.
• *Check if the cable from touchpad to the main control module is faulty.
If it is a faulty cable, then the cable might have to be replaced.
• Check if 'Spill is activated' is displayed on the LCD screen.
• Check if 'Spill' status is displayed for the Group status in the home
screen. Opening other zones will rectify the error
• *If all zones are turned on but the total opening percentage doesn't
meet the required spill percentage, then the SPILL warning message
will be displayed. Increasing the opening percentage of a few zones
will resolve the issue.
• *Check spill set-point.
• *Check if the cable is plugged in properly. Unplug the cable and
reconnect it.
• *Check if there is power to the unit.
• Reset LCD by holding RESET button at the bottom of the Touchpad for
2s.
• *If error is still not resolved, reset touchpad by unplugging the cable
from behind and then reconnect it after a couple minutes. If the
corrupted display remains, power off/on the mainboard. Otherwise,
replace the touchpad.
• *Check Grouping and find out if the right zones have been assigned to
the right groups and have been turned ON/OFF in Zoning section.
• *Check if the total group number and zone number are correct.
• *Check if the LEDs on the main module light up for the relevant zones
when the zone dampers are turned On/Off. If there is no response,
there might be a faulty cable and the cable would have to be replaced.
If the zone is still non-functional then there might be a faulty damper
motor.
• *This error is displayed due to a fault with the AC unit. The AC ON/OFF
function will be disabled when this error is displayed. Please check the
AC unit / AC touchpad to fix the problem.
