Warning:
Use class II category transformer for 24 VAC power supply. Do not ground either of the 24 VAC lines! Failure to do so can
result in internal power supply damage.
We recommend the use of separate transformers for 3
rd
party controllers, to avoid possible grounding problems in the power supply.
