I want to install a Tekmar 260 control on my non-condensing boiler. I have one zone for heat and one for DHW. Each zone has a Taco 007 circulator.
I want to be sure the relays internal to the 260 can handle the 007's in the long haul.
The 260 specs are below:

The 260 I/O seems to indicate direct connection to the circs. I just want to be sure the internal relays are sturdy enough.
