I'm working on a Brutus clone that uses three Honeywell VR8200 gas controls. I'm trying to figure out the amount of power required for the 110VAC->24VAC transformer. Although it will probably never happen, I'd like to have a transformer big enough to run all three gas controllers at the same time. The manual for the VR8200 (found here) claims the following:
Hold-in current: 300mA max
Drop-out current: 250 to 90 mA
Thermostat heat anticipator setting: 0.5A.
Do I need to include the anticipator in overall current consumption, which would basically mean that each VR8200 uses 800mA? If so, then I'm looking for at least 2.4 amps of 24VAC. That would mean a transformer at least 60VA?
I'm pretty sure I know what the heat anticipator does (i.e. account for overshoot), but I don't know how it works, so I don't know how the 0.5A spec applies to the overall power consumption.
Thanks,
BB
