Functionality is good, but overshadowed by the cost.
The cost of the product is too high versus functionality. The do have decent technical service, but the wait time is too long

To many options
We want to control heating boilers and pumps. It seems that Telmar always want to through in water heater control also but are lacking on the pump control. For the money it is a good control, controlling warm weather shutdown, reset and the main building pumps.
