The problem i am having is zone 4, zone5 and zone6 sometime having fast cycle on the furnance. Could there be a possibility of wiring error by the old installer?
Or should I replace the old thermostat to simple digital type themostat (non-programable) for better accuracy in temperature detecting? Please advice and thanks

All zone thermostat anticipator are set to .4
6 -- honeywell mercury thermostat w/ anticipator white and black wire
6 -- honeywell zone valve, yellow1, yellow2, orange1, orange2 wire
2 -- 24v control circuit stepdown transformer label R and C
zone 1 to 3 are all 1st floor
zone 4 basement
zone 5 2nd fl master bed
zone 6 2nd fl other bed room

white wire – thermostat W
black wire – thermostat R
========
zone 1 themostat black wire to zone valve 1 yellow1
zone 2 themostat black wire to zone valve 2 yellow1
zone 3 themostat black wire to zone valve 3 yellow1
themostat zone #1,#2,#3 bundle to a white wire to 24v transformer1 "c"
zone valve #1,#2,#3 yellow2 wire bundle to a black wire to 24v transformer1 "r"

THIS IS THE PART I FEEL THERE COULD BE AN ERROR
zone 4 themostat black wire to zone valve 4 yellow1
zone 5 themostat black wire to zone valve 5 yellow1
zone 6 themostat black wire to zone valve 6 yellow1
themostat zone #4,#5,#6 bundle to a white wire to 24v transformer2 "r"
zone valve #4,#5,#6 yellow2 wire bundle to a black wire to 24v transformer2 "c"
SHOULD I SWITCH THEM TO AS FOLLOWS?
themostat zone #4,#5,#6 bundle to a white wire to 24v transformer2 "C" INSTEAD
zone valve #4,#5,#6 yellow2 wire bundle to a black wire to 24v transformer2 "R" INSTEAD
