Question about Heating & Cooling

Open Question

Hi Heatman101! My wife had a new Bonaire Pyrox Vulcan in wall heater installed in 2009 while I was on military deployment. I've now retired and moved from the U.S. to our home on Melbourne, Vic, Austrlia (so this is a 240v system) The unit had a few intermittant faults (Err F1 or Err 1) last winter, but has started to have these faults every day since being placed back in use 3 weeks ago. The 2 year warranty expired last month, of course. The unit gets power, but the heat and fan functions stop when this error code appears. Usually the heater runs for 5 to 60 minutes before the fault appears. F1 is just a general fault code, so it doesn't tell me much. Any ideas? Thanks!!

This unit is a cooling unit only. I don't know what switch you are looking at but I don't think it's for the evap. cooler(swamp cooler). I am in the Phoenix, Arizona area and it's very common to have a evap. cooler and a seperate heat/cool system as on the hottest days the evap. cooler doesn't cool enough. I hope this helps. Please give me a positive rating. Thank you.

SOURCE: My compressor will not start.

There are a few more things to try, in the control unit of the AC there is Cold Control/Freeze Switch. Take down the control unit (inside unit, remove inner shroud) and remove the cover, The freeze control is plugged into the blue plug on the board. Remove the plug and install a jumper wire in its place. Does the compressor come on? If so, you have a bad freeze control. If not, then we need to check and see if your AC power module is sending power to the Compressor. Check power across the relay in the control unit, Black to Blue. If the blue wire is hot, then you need to go upstairs to the top of the compressor and check the thermal overload. If the blue wire is not hot, the comfort control center may not be sending a signal to turn the compressor on. If it is not, do a reset of the CCC. For a five button system, turn the tstat off and hold down the Mode and Zone buttons simultaneously. While holding them down, turn the CCC on and hold the buttons until FF appears on the screen. Release the buttons and try the AC.
Four button reset -
Depress MODE switch to activate annunciator light.
Simultaneously depress the bottom two buttons
(temperature UP and DOWN) and hold.
While holding these buttons down, depress the
MODE button once and release.
Release the two buttons previously held down.
Depress the MODE button once again.
At this time the light should extinguish, and the mode
should register “OFF”. If not, repeat Steps 2 through
Retest system ensuring that all functions are present
and operational.

Hope this helps,


Rate me please!!

SOURCE: Pyrox Vulcan Wall Furnace 2

In the manual they did not discuss the meaning of error code of F1. They says call service center if yu see F1. You have already done that. So follow his instruction.

Does Vulcan Pyrox gas wall furnace have a filter? It seems to cycle on and off too often and the gas seems too high. Also it makes a bang when reigniting. How can I turn the gas down inside it?

get it serviced by a licenced gas fitter / plumber. Should be serviced every two years. Don't risk your life via carbon Monoxide poisoning get a licenced gas fitter /plumber to assess the unit.
