hey guys have a problem with my install. I changed jobs from being an installer (hvac) to working in builings on boilers and roof tops. So Ive been out of the loop. my problem is is hooked up the 2 brown wires on the 700 directly to the humistat both on (h) next I ran the white wire from common on the board to the c on the humidastat and took the red wire from HUM to the r on the humistat also I have this set up in manual so no outdoor temp sensor used. were did I go wrong with my wiring the furance wont kick back on and I dont want to fry the board. I was hoping not to use a model 50 relay. thanks for your help. If any one can help email me please

Don't post email addresses.
Bots find them and then search the rest of the system slowing it down.
Your first mistake was not reading the install instructions of both the humidifier and your furnace/heat pump.
That will cost you now.
