pump/loop valve burps on cron_min run

For some reason, the cron min is momentarily writing pin ON when the heater control is should be off. 
The pump and loop valve are the same relay (one connected to the NC, the other NO side of the relay) but it's also flipping the Pump relay too. Once a minute that relay is flicking on/off as the cron run over the code. I can't seem to figure out what is doing that.
