Department: Johnson Capillary and Space Thermostats
  Johnson A28 Series Thermostat A28qj-9100
    FEATURES
• Liquid filled sensing element
• Dust tight PENN switch
• IP65 protection class models available
• Front adjustment
  2-Stage Thermostats, IP30 & IP65 Controls are compact with fixed differential per stage and (on most models) adjustable differential between stages. Liquid filled element provides wide range, constant differential over whole range and no influence from barometric pressure. Since the bulb contains the major portion of the total fill the thermostat may by considered as crossambient, capillary and cup temperature variations affect the operating point only slightly due to the small amount of fill they contain. For quantity orders it is possible to have the below stated optional constructions: - Without case and cover for panel mounting - Close differential per stage - Different capillary lengths All standard IP30 enclosure models have a universal way of adjustment. For this purpose a knob and sealing cap are enclosed.

APPLICATION
These thermostats are designed for various types of heating, cooling, ventilation, or air-conditioning applications. All models have two SPDT switches providing the following control possibilities: - 2 stage heating - 2 stage cooling - Heating/cooling with automatic changeover
Manufacture: Johnson Controls
Notes: A = General purpose
Stg = Stage, Bet = Between
B = Bulb stainless steel
C = Max. bulb temp. 85°C
D = Concealed scale
E = Screwdriver adjustment
F = 3A switch
Sizes - 125 x 55 x 46.5mm (IP30 types), 125 x 60 x 59mm (IP65 types)

Very quick delivery and extremely happy with the part and service !
...David Bingham
I was very impressed with the service given my MyTub. As I was moving and it was a bit complicated with delivery I was worried that things would go wrong but they didnt. I could always get through to somebody straight away on the telephone who was knowledgeable about the situation and all went smoothly. I am so pleased with the Katell Galaxy fireplace. It is just as described and looks really good in my new home. Thank you for your customer service.

MyTub have gone way beyond the extra mile in fulfilling my order after items went missing in the post. Even though the problem was not of their making, the customer service team have been second to none and they stayed fully focused on my order until all issues were resolved and for this they have my gratitude. In general, I found MyTub very easy to deal with and the whole experience for me was positive as they provide an excellent level of service, quality components and very keen prices. Ordering was very easy through the desktop website and although I did not have need to use the mobile version, I have no reason to think that there would be any issues.
