Cobalt neotherm hooked up to chiller?

[Solomonster]

I have a chiller that has a optional external function. I also have a neotherm and was wondering if it would be okay to plug it in to the chiller. Not sure if the constant on and off will damage the heater. Also if it does what would be a good heater to go with?
Thanks
