Resistors for power stealing thermostats

[scottz]

I am replacing the manual thermostats on a 3 zone boiler heating system with Honeywell T8775A 1009 non-programmable digital thermostats. The new thermostats came with a resistor pack that included instructions to install when using Taco zone valves. I have Honeywell V8043E1012 zone valves; do I still need to install the resistors?

Thanks
