24 V (ac) Powered Outputs
The 336 has an internal transformer that provides powered
outputs for up to four 24 V (ac) 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.
115 V (ac) Powered Outputs
The 336 has five internal relays that provide powered outputs
for four zone pumps and one zone group pump.
Refer to the Job Records to determine the allowable loads
for these relays.
Sequence of Operation
When a thermostat calls for heat, the Zone LED turns on
and the Zone relay is turned on.
• • If the Zone Group Pump DIP switch is set to On, the
Zone Group Pump LED and relay turn on.
• • If the Zone Group Pump DIP switch is set to Off, the
Zone Group Pump LED and relay are not turned on.
Pump A Demand
To operate the Zone Group Pump A relay externally, a
powered signal must be sent to the Pmp A terminal on the
336. Refer to the Wiring Brochure for the proper wiring.
Zone Group Pump
Each zone has a corresponding Zone Group Pump DIP
switch.
Zone Group Pump DIP switch set to On:
•
• The Zone Group Pump turns on when the zone calls for
heat.
Zone Group Pump DIP switch set to Off:
•
• The Zone Group Pump does not turn on when the zone
calls for heat.
