- NADA Controller. FREE SHIPPING!*
Description:
The NADA Controller consists of: - Vegsensor (turns Vegtherm off at ~ 80C), chrome handle on/off toggle switch, a "forgot-to-purge" buzzer, and one of our MFT timer relays (with their required 4-pin additional relays).
One MFT timer function can be set to correlate to observed engine coolant temperature, and is easily adjusted to user preference and/or seasonally. (For example, watch coolant gauge on a cold start, drive car, when coolant is up to operating temperature observe elapsed time. Set MFT accordingly - this should not change much from season to season if your thermostat is working correctly. If you don't want to be bothered changing it summer to winter, just err on the longer side. For example, if it takes 3 minutes to reach operating temperature in summer and 6 minutes in winter, set it for 6 minutes). Note - you do not have to use this feature if you only want to use the MFT for a "staggered" purge ("delay-off") - see below.
The second MFT timer function is for the "delay-off" for the "return" valve. Note that you can also set a "delay-on" with that timer, such that the return valve does not switch to veg at the same time as the supply valve, so if you are running a "return-to-tank" (veg tank, that is), you can minimize the amount of diesel going into the veg tank (and hence buy even less diesel!).
Any "Controller" offered by anyone has these same basic functions, and any of them require same user input. There is no display with this unit, it is simple, robust, and inexpensive. Users can add LED lights if desired, to indicate status of timers/valves.
