How can you clear alarm 1 on a Honeywell UDC 3500 controller?

What parameter needs to be set to clear alarm 1 on a Honeywell UDC 3500 controller?

Answer:

The parameter that needs to be set to clear alarm 1 on a Honeywell UDC 3500 controller is A1S1TYPE.

Clearing alarm 1 on a Honeywell UDC 3500 controller requires setting the A1S1TYPE parameter to a specific value. In this case, you need to set the A1S1TYPE parameter to 0.

The A1S1TYPE parameter in a Honeywell UDC 3500 controller should be set to 0 to clear alarm 1. The 'A1S1' refers to 'Alarm 1 Setpoint 1' and 'TYPE' refers to the type of alarm. Setting to '0' means disabling the alarm, effectively clearing it.

Explanation:

To clear alarm 1 on a Honeywell UDC 3500 controller, one has to set the parameter A1S1TYPE to 0. This is because in the Honeywell UDC 3500 controller, the A1S1TYPE parameter determines the type of alarm 1. Setting it to 0 means that you are disabling the alarm, which effectively clears it. The 'A1S1' in A1S1TYPE refers to 'Alarm 1 Setpoint 1', and 'TYPE' refers to the type of alarm. Thus, to clear the alarm, you need to change the type to '0', which is the setting for no alarm.
