Temperature Limiting
Temperature limiting can reduce energy costs by limiting the lowest temperature that can be set for cooling and the highest temperature that can be set for heating. Temperature limiting is controlled by setting the first six auxiliary switches.
The first three are used to select cooling range limits and the next three are used to select heating range limits.

The Zoneline has a diagnosis feature. When switch D is moved to the UP (on) position, the unit will go through an operations check of all components which takes about two minutes. This diagnostic tool is intended for use by a qualified technician.
