Don, don't let them make you launch the Yellow Fire Bomb before you are ready. Even a test fire is fine. I see you are wiring now, and I'll PM you with a couple answers to your questions.
Was that insulated pex 'Everything you hoped it would be?' Kinda want smoke a ciggy afterwards? It comes close to being the most fun you can have in the winter WITH your clothes on.
Usually we add a taco or other circ/zone panel to simplify things. You can get an 89A, 501, 502, 503 Taco or Honeywell or something similar for one additional circ, or if you are adding 2 or 3 more, a taco or argo would be nicer...all in one place, easy to wire, easy to test, fuse protected, transformers are built in....... I don't know about your Honeywell and am looking, but remember in the back of your mind that some of them don't start the circ until the aquastat reaches 140 degrees (or the low limit). Zero start ones let the boiler drop off, however you won't be going there.
Just as I was gonna send this, I saw Rob mentioning the circ energizing at the low limit. I never use the aquastat for circ control, simply because if the fire goes out for any reason, the circs are independent, on a different control, and can run in below freezing conditions. This is unusual for most heating guys, but I'm different that most heating guys. In 1976 I was called to a house that ran out of fuel. It was -23 and the wind was blowing. Every f***ing heating pipe INCLUDING the boiler froze and burst before we could get it back on line. We has a generator, fuel, filters etc. with us and still could not save it. (6 hrs after it was first found) That was the last time I wired anything to the boiler controls. 128,000 dollars in damage.......and the oil company had to EAT IT because the people were on 'auto=fill' AND someone forgot to fill it!!! Now the circs run all by themselves controlled only by the thermostat(same with zone valves). Running water will not freeze.....and yes in 1982 I went to a house that we had set up that way and the boiler was propane....and guess what....no auto fill. My thermometer read 17 degrees, and the heat pipes did not burst of freeze up. We have a hundred lb propane tank in the truck and 2 20's, so we ran a space heater (250K) off a 20lb and hooked our 75 foot rubber hose to the gas line outside and refired the boiler. The 250K heater had it warm before the boiler recovered, but it makes your heart pound!!!!
Taco Switching Relays:
Single Zone Taco Switching Relay (SR501) is a standard equipment for every installer and replaces any other switching relay from any manufacturer. Regular 2 through 6 zone models (SR502 through SR506) and expandable (-EXP) models offer the most effective, reliable and easy-to-use means of zoning with circulators and are installer's best choice.
Taco Zone Valve Controls:
These controls are designed for zoning with valves, such as Taco's 570 Gold series and offer easy-to read PC board layout, compatibility with nearly every 2, 3 or 4 wire zone valve brand and instant diagnostics through external LED's.
Various models of Honeywell Aqaustats (a.k.a. Aquastat Controllers) are designed to regulate and control boiler temperature, injection mixing circulators & valves, as swell as floating control mixing valves.
Honeywell Aquastat Relays:
When you need a controller which combines the functions of a switching relay and an aquastat (or an immersion type control), Honeywell Aquastat Relays are the all-in-one solution. All models come with a built-in transformer to provide power for the low voltage control circuit and select models are available with damper or zone valve control interface and terminals for adding remote low limn temperature regulator.
Honeywell TrueZONE system:
This equipment line is packed with features such as variable speed fan control, discharge air temperature staging and advanced dual fuel operation and presents a versatile and straightforward solution for control of heat pump, conventional or dual fuel systems.
Taco Boiler Reset Controls:
The major duty of these modules is to control the supply water temperature based on the outdoor temperature, thus matching the heat lost from the building is by the heat input to it. By using Taco boiler reset control, boiler's firing cycles are optimized, comfort level and savings are increased. There's no sophisticated wiring - simply connect the Taco PC700 series with any of the EXP switching relays, install the sensors and let the system do the job.
Low Water Cutoffs by Taco:
Low water cutoffs are standard probe-style controls which monitor the fluid level in boilers and engages when the water level is below the minimum safe operating level specified by the manufacturer.
