Question about Heating & Cooling

1 Answer

Hi there I have had a siemens thermostat RAA02/03 fitted to control the heat transfer kit in my house. Something is amiss, I think, in that when I set the thermostat to a temperature well above the actual room temperature (eg set to 30degrees when actual room temp is 15degrees), the thermostat is switching on the fans in the heat transfer kit and when I have it set lower than the room temperature (eg set to 15degrees when the actual room is at 25degrees), the system is switching off. It is my understanding that when the room temp exceed the thermostat seting, it should be switching on and transferring excess heat to other rooms and shutting off once temp has been reducede below the set temperature. Can you help me please? Bruce Perry

Nope...this is just a misleading in their way to express teh function ...the actual thermostat you are setting will only regulate the temperature in accord with the room it is installed into ..and the only way will blow to the other is when it is on ...and until the room it is in will get to the temperature set ..after that will switch of until the difference will start it again ..
To do what you said..you have to have one that supports this feature ..and it has thermostats in each room so to make the transfers in according with the heat detectors of each room and the values set for each ..and I dont think this one is that complicated..if it is ..it needs a proper setting in the menu ..set to transfer excesses to the other rooms..and set the temperatures in each room ..and enable it ..
if your do not supports this kinda setting ..I guess it is not what you thought ..and it just warm or cool in accord with the settings and the temperature detected in this room where it is installed..
I guess it can be made to do this kinda job..but you need to place more than one thermostats ..one in each room ...but the risk is that rooms will heat in different mode..and it will detect temperature drops in on e..and start and heat all.. or will be in error cause one will try to start it ..and the other to shut it down..

Fraser Johnston Furnace - Not heating


Check the furnace filter to make sure its not dirty . Dity airvfilters can cause the furnace to overheat and shut off on a high temperature limit switch when the switchs cools down it resets but the furnace has to be shut off to reset the control board. Hope this helps.

Belling cookcenter oven over heats and light stays on


It sounds like the people who changed the elements did not connect them to the correct wires. The thermostat seems to have no effect on the elements, and the light switch seems to have no effect on the light, explain this to them and that you think they fitted the elements directly onto the power input to the device, instead of the correct connections.

Siemens rdj10rf/set-gb problems with


There seems to be a common fault with the relay in the base unit box that's wired in to the boiler. If the black triangle is showing, the remote is demanding heat. If the two lights (green and orange) on the base unit are both lit, then it is paired and knows that heat is being demanded by the remote. However the relay sticks and doesn't actually supply current to the boiler. It can also stick in the on position so the house just keeps getting hotter. I've found that a couple of firm taps with my knuckles on the front of the base unit usually solves the problem temporarily, but if it keeps happening I think you need a new base unit (although I think you can only buy the complete kit).

Siemens defrost controler


turn the defrost cycle switch till the compressor shuts off, if the defrost heater starts working you know it's the cycle switch. Sometimes the thermostat has to be showing a need for the heater to even come on. In
this case you might have to jump out the thermostat to make the
heater come on. If you thaw the back of the freezer and visually inspect the heating element it can sometimes have burnt ends that will tell you
it is bad. You could also use a voltmeter and track where the voltage stops. But make sure the Thermostat and defrost cycle switch will be
calling for heater to come on.

I have a 1994 Jeep wrangler 6 cylinder. I replaced the cooland and therostat and it opens like it should at about 100 but the air is still cold. Is there something I overlooked?


Hello! Thermostat should be a 190 degree...you may have an air blockage...Remove radiator cap start engine and leave cap of until all air bubbles are out (even after thermostat opens)...Cap and test for heat...if there isn't any heat...When that thermostat opens and hot water flows through the upper hose of the radiator that hose will be hot and hard..If you feel the heater hose only one will be hot which means that nice hot water is not passing through the heater core...That could be due to blockage or the control in the car isn't opening the valve on the core...check to see if the heat control is opening the valve...If it is, I would suggest that you purchase a back flushing kit ($10) A plastic tee fits into the inlet heater hose and a garden hose is then connected to the tee...Drain the radiator, remove the thermostat, and turn on the water...do this with heat control on high...The system will back flush out of the top of the radiator and hopefully clean the blockage...Reassemble ...Cap off the tee (cap is in kit)...Install thermostat (190) Is a better choice...Refill radiator...Start engine and leave the radiator cap off until all the air bubbles out............At that point you should have heat...Guru...Saailer

I have two heatpumps up and downstairs and two furnaces (piigy back). At times my pump outside freezes up and cold air blows in the house. I was told that I needed a kit to tell my furnace to turn on when...


Hi,
A couple of things... First your furnace should be 2nd stage on a 2 stage thermostat and if the heat pump don't keep up your furnace should be coming on anyway...If you get a Honeywell Vision Pro 8000 series thermostat for 2 stage heat pump operation and an outdoor sensor, you can have the thermostat shut down the heat pump and start the furnace at what ever temperature you decide...

Secondly, you have a problem with the defrost cycle on your heat pump(s) If they are frosting up that bad at 40 degrees than the defrost is not working on them. If they are hookup up right, every fours hours or so they will go into A/C mode and heat the oudoor coil up to melt the ice off of them. The furnace should be heating while that is happening. Sounds like they really don't know what they are doing when it comes to heat pumps...

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

The dryer turns on but no heat is this the heating element or something else?


Most likely it is the element. The only way to be sure is to visually inspect it.

Amana HTM (heat transfer module) system


I would check the house thermostat(and its wiring to the indoor unit), and if it's OK then check the heat transfer fluid diverter valve inside the indoor unit (should be sending the hot fluid through the big radiator (air exchanger)) until the surface temperature of the radiator is approximately 130 degrees F, then the fan control operates and the fan starts to blow hot air through your ductwork. My HTM is 26 years old and I've had many opportunities to "hone" its operation...
