THG vs flexwatt?

[Syfaio]

You said one of your connections of heat tape. How many connections do you have and how many connections per probe on the thermostat? How are they wired?

It's a 2 level rack so each level has a connection both are 3.5ft and 6inch THG both directly plugged into the thermostat
(The probe is directly on the heattape itself)
