An actuator means for a remote temperature control unit includes a base member onto which an edge of a diaphragm is crimped, a ring of solder is placed on the base member adjacent the crimped edge of the diaphragm. This assembly is placed in an oven in an inert environment with the temperature at about 575.degree.-585.degree. F. for about three hours. The temperature is then raised to 615.degree.-625.degree. F. for about twenty minutes to melt the solder to sealingly solder the diaphragm to the base member. The oven is cooled to about 250.degree. F. while it is in an inert condition and the finished assembly is removed from the oven.
