Not sure if anyone can help but throught I'd throw this out...
I have a Pentair Easytouch automation panel with a Pentair MasterTemp Heater. The heater works fine when operating it from the panel on the heater but not when operating it from the panel. I have verified the heater is activated in the panel and a setpoint is established. I have a two-wire connection from the automation panel to the heater. It is connected to the 24VAC fireman's control switch in the heater. Based on all documentation I can find, the connections are setup correct. What I can't determine is how the heater should act when functioning from the panel. My theroy is that when the panel is told by the temp sensors connected to the panal that the water temp is below the setpoint, it should apply 24VAC to the fireman's control swich and turn the heater on until it reaches the set point. Then, it should turn the heater off. Is this assumption correct? If so, then I've got some problem which I will need to hunt down. Because my panel is not doing anything to control turning the heater on.
Thanks for any input/insight anyone can provide.
