Carrier 30RA013 cooling past setpoint
Hi, I have the carrier 30RA013 water chiller with pro-dialog control panel and I have set the setpoint to 0 degrees C (returning water temp). The unit is cooling until -2.7C then cuts off (no alarms). Unit starts cooling again approximately at +0.7 or +0.8C. How can I adjust these limits? There is no such option in the pro dialog manual nor in the user manual (from http://eto.carrier.com/lit.asp).
Is it maybe in service menu? I have the password (113), but I don't know what structure of service menu.
Thanks in advance if anyone can help.
