Does anyone know where I can buy spare 4-pin female communication cable connector/leads that come with these thermostats? It's used to connect the CAT5 coming from the HAI panel to the 4-pin male connector inside the RC-80. I've renovated the house but the original 4-pin connectors were inadvertently discarded. I'd like to reinstall my RC-80's but don't have the 4-pin connectors that's required to wire the RC-80 at their new locations. Many thanks in advance!
