24 V (ac) Powered Outputs
The 335 has an internal transformer that provides
powered outputs for up to six 24 V (ac) zone valves and
six thermostats.
The internal transformer has limited power available. Refer
to the Job Records to determine the load on the transformer.
If the load is too large for the transformer, refer to the Wiring
Brochure to add additional power to the system.

The 335 has an internal relay that provides a powered
output for a zone group pump.
Refer to the Job Records to determine the allowable loads
for this relay.
