Relay Symbol ?

Hi,
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 (goint 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 sybols.
Could it be meant to be the coil for the relay, perhaps ?
Or,... ?
Thanks,
Bob

Sometimes what you described is used to indicate a solenoid.

It is a relay coil or a solenoid coil. Relay coils are generally circles, but I have seen the solenoid symbol used as well.
