Dimming vs Pulse Proportional?

[JobForARetic]

Picked up a new thermostat for use with our Animal Plastics rack that uses 4" heat tape. Is one mode better than the other for this as it can do either or?

In my experience, Pulse is better for heating mats& tape and on/off is better for heating bulbs & panels.


Also, on/off can be better if your room is cold and has the possibility of sudden temperature drops. For example, if my room suddenly drops to 59 degrees, I want my heating element to turn on at 100% power, not the 29% power that was necessary a few minutes ago when my room was nearly 70 degrees.
