Based on the available Honeywell documentation, the temperature limit is adjusted through the controller menu using Select mode and Setup mode on the UDC1200 platform. The literature also confirms that the UDC1200 limit controller can be configured as either a high limit or a low limit.
However, we do not have a clearly DC120L specific step by step programming sequence for setting the limit value. Because this is a safety shut off control, we strongly recommend using the official model specific user manual or having the controller reviewed by a qualified technician familiar with your equipment, application, and local codes and safety standards before making changes.
