Fixed switch differential
On controls and recycling limits a fixed differential of: 

4 ± 1.5°C, 8 ± 3°C or
12 ± 3°C is supllied as a standard.

Optional are: 

7 ± 2.7°F,
14 ± 5.4°F
15 ± 5.4°F

Adjustable switch differential
On controllers and recycling limiters an adjustable differential 
of:

4 ± 1.5°C ... 10 ± 3°C or
7 ± 2.7°F ... 18 ± 5.4°F can be supllied.

Manual or tool reset switch differential
On the thermal cut-out versions (manual or tool reset) of the 
panel mounted, the single direct mounted and the dual direct 
mounted Aquastats the maximum reset differential might be 
30°C 

NOTE:

The differential (thermal) is dependant on the rate of 
change of the temperature in the heating system. 
The given differential datas are valid for a rate of 1°C 
per minute.

An ambient error ratio of 1 : 6 means that an ambient 
change of 6°C will cause a setpoint shift of the Aquastat of 
1°C.

Time constant
• With well 

τ ≤ 30 s for panel mounted, single direct mounted, dual 
direct mounted and triple direct mounted Aquastats.

• Without well

τ ≤ 4 s

• With sensor assy (Surface mounted Aquastat)

τ  ± 50 s
