Got the GEYA timer rely in yesterday and hooked it up. Dialed it in over a number of cooling cycles. Settled on a 4 minute delay on the radiator fans to allow the Peltier units to drop the cooling water temp. down to 11.4*C (measuring the temp. in the reservoir) before starting air circulation to cool the chamber. This is the temp. of the water before it enters the first peltier unit where the temp. will drop an additional 1*C prior to flowing into the first two radiators.
3*C is 5.4*F; and a larger delta than start up with the fans running. That larger delta helps tremendously with faster cool down as water being more dense than air can hold 25X more heat than air. This is a kind of reserve affect...
I plugged in my spare temp. controller and put the temp. probe in the reservoir to monitor it. it was at 11.4*C but flipped to 11.5 when I snapper the pic.
This is the chamber temp. controller temp. at the start of cool down.
I just watch the RH% controller and if the RH starts dropping then I know the cooling water is too cold.
