      From: stereobuff07@gmail.com              "Bob" wrote in message news:l0l7mk$m8l$1@dont-email.me...              Hello,              Have a forced hot water system for home heating that uses the typical 2       wire Honeywell thermostat to control a Honeywell RA832A switching relay.              The switching relay closes the circuit to the thermopile, as well as       closing the 110 V circuit for the water circulator.              There is also a transformer that provides 24 V for the thermostat and       the relay.              Question:              Guess I'm dating myself somewhat here, but there is a symbol that I am       not familiar with in the instruction sheet for it.              The secondary of the transformer (going to the thermostat) shows what is       similar tho the common resistor symbol of       3 points up, and 3 points down from the baseline.              But this symbol has only 1 point up, 1 point down, and then the return       to the baseline.              I don't think it is meant to be a resistor.              It is drawn close to the relay contact symbols.              Could it be meant to be the coil for the relay, perhaps ?              Or,... ?              Thanks,       Bob                            I is probably a symbol from those damn aliens. They were getting into       everything back then!              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
