I have two controllers in parallel to a bathroom fan: Honeywell HVC001 and DewStop FS-100. The DewStop functions properly but the Honeywell apparently resets its clock/timer whenever the DewStop powers the fan (otherwise the Honeywell operates as specified; the Honeywell control display will blank out while the DewStop is running the fan.) How should I connect these in parallel (or what do I add?) Honeywell's tech support says that they've no ideas or suggestions. While I could rewire these controllers so that only one controls the fan, both are required for this application (one be city code; the other by user specification.)
