This was a line check. We had 6 MELs total. [One MEL] was added by me when I discovered the 1B pump would not pressurize the system. This set us back. After everything was signed off; we ran remaining checklists. We then pushed back off the gate. Even though it was previously briefed; the Check Airman was pretty sure the 1B pump switch should be on. I pulled up the MEL again which stated it should be off. We begin taxi on one engine. Temperature is 6 degrees Celsius. The First Officer asks if I want the cowl heat on. Expecting to start the left engine shortly; I stated no and the reason why.Crossing Runway 5 on Golf; I gave the command for delayed engine start. I was greeted with a bleed misconfiguration caution message. The cause of which was the cowl heat being on; not sure why. The Check Airman stated that cowl heat needed to be on. I replied I can't start the left engine with the cowl heat on.After the left engine was idling and the Delayed Start Checklist was complete; we moved onto the Before T/O Checklist. Cowl heat was on. Wings Anti/Ice was off. The temperature was 6 degrees. We were configured according to the weather conditions and the Dispatch Monitor. The Check Airman then informs me we must takeoff with wings and cowls on. I respond by noting the ATIS is indicating 6 degrees and that SAT is 6 degrees. The ceiling is 400 Overcast.At this point; I believe I am in compliance with POH limitations. My First Officer then proceeds to send for new numbers with wings and cowls operating. The check airman told her to do this. I did not. After about three minutes; I elected to takeoff with wings and cowls operating to prevent any further drama.I have never seen this happen before. With weather conditions according to POH. We were within limitations to depart cowls only.
Air carrier Captain reported poor CRM on the flight deck leading to confusion during the taxi-out and preparation for takeoff.
