Dimplex products are typically sold at most Home Depot and professional electrical supply houses. However, they rarely will have all the literature for those products in their stores.
Dimplex once provided an online list for all their heaters and thermostats, but no longer have the product manuals available on their website for customer download. They make both 120V-AC and 240V-AC versions and several different models, so I can't safely provide you with the wiring connections, since each installation is different and depends on the type of thermostat and heater(s) being utilized.
So now that I've given you the bad news, let's move onto the good news!Dimplex now uses an online request form for customers to get manual and literature on all their products. They'll send you the manual for your Dimplex product free, once you submint the request.
Here's the link to the request form for you to fill out and submit, just have your model number handy and you should be all set.
Hope you find this Very Helpful and best regards!
