Surface Mounted Thermostats
Surface mounted thermostats are mounted into a bracket which holds the thermostat against the side of the tank.
Surface mounted thermostats respond to tank surface temperatures to sense a call for heat, set point temperature
settings and high limit (ECO) activation. It is import that the entire back surface of the thermostat is in full contact or flush
with the tank. Improperly mounted thermostat will lead to improper heater operation.
