I have a tank with how water supply/return through the
tank. The tank OT=60 degree C, and the discharge pump
OT=50 degree C. I try to decide what is approiate
High/Low temperature value. Could I just use High Temp alarm =70, and low temp alarm=50. But I am afraid
that the low temp alarm 50 degree C may cause that on-off
valve action too frequently.

Could anyone profesional give me a suggestino?

Thank you very much for your help.
