My new autopilot dig-220 with SC-60 arrived last night. I was planning on installing it this weekend with my new timer (intermatic PE-153). After reading the installation instructions on the DIG-220 they mention an OPTIONAL PUMP RELAY but I could not find one listed on their website. My plan was to wire the SG to the first circuit in the timer and wire the pump to the sg then my cleaner pump on the 3rd circuit run it in mode 3. I guess i need the pump relay. does anyone have a source for the relay or another idea to wire it without the pump relay.
