Wafer for thermostat (New model)

This wafer is used for the thermostat #120. It's a spare part that goes into the incubators #1602, 1583 and also in several older models of brooders.

A bracket is included with the wafers and must be changed on the incubators, as the gas inside each has been changed and theses new wafers expands more than the older model #T7
