| Application |
These controls are designed for use in chillers or in applications
where there is a request for manual resetting of the process. |
| |
| Installation |
These should be installed in a place which is free of vibrations, water and corrosive gases or vapours and where the ambient temperature does not surpass the value indicated in the technical specification. |
| |
| Function |
The primary function of these controls is to act as a safety device and shut down the process before freezing takes place.
Freezing in devices within the system as we know can be disastrous and lead to expansion which inturn will cause cracks
and leaks.
SZ-7514-P is a combined temperature and antifreeze controller. |

| Probe location. |
Particularly in the 7512-P / 7514-P controls, an accurate reading is very essential. The very function of the controller depends on the precise feedback it gets from the sensor. The probe installation must be free of heat influence other than the temperature that is being regulated or sensed. The probe and its cable should NEVER be installed in a conduit along with power control or power supply cables. |
