Hi,

Looking for some assistance to determine whether the temperature controllers from Toto are interchangeable?


I am looking at purchase a wall-mounted Toto Helix Faucet Trim Only which is an electronic faucet that requires a temperature controller. The manual shows that the faucet wires up to either a TELC105-D10E or TELC101-D10E.


I have an older Toto TN78-10V710 temperature controller lying around and was wondering if I can substitute this controller with it?

I understand that the TELC105/TELC101 controllers have a single supply into the unit where as the TN78 units have two supply lines running into it Hot and Cold. Which basically seems like the TN78 has the mixing valve built in. The TELC105/101 requires a separate mixing valve before the unit TLT10/TLM10.

Any ideas if I can use the TN78 controller in replace of the TELC105/101 controllers? Any assistance is greatly appreciated.


Cheers,

Kevin
