7.3  Internal control functions “H.M” and “TW OFF”  

These  functions  have  already  been  described  in  detail  in  sections  0  and  0  in  the  Chapter  on 
Operation.  They  are  summarised  here  again  in  brief  since  they  are  also  used  for  monitoring 
operating  safety  and  are  significantly  influenced  by  external  parameters.  These  are  control 
functions,  not  actual  errors,  since  they  are  the  way  the  appliance  responds  to  external 
influences / operating parameters.

How to correct error  
 

H.M = 

 

Internal Modulation; see 
also Chapter 0 

 

 
This is a control function 
rather than an error. 

 

 

The temperature limits for the 
exchanger, TW, or flue gas fan (TR) 
have been exceeded, and the appliance 
powers down to minimal load until the 
limit values are met again. This is a 
control function (not an error), which can 
be activated, for ex. by excessive flow 
temperature (too little heat transfer via 
water) or use of pellets with excessive 
calorific value (average output above 
nominal thermal output) or high ambient 
temperatures. 

 

 

TR

max

< 200 

°C with 6 K 

hysteresis (all 

models) and 

for Waterplus 

models 

additionally 

TW < 75 °C 

with 6 K 

hysteresis 

 

 

A soon as functional values 
have dropped to desired 
range, allowing for hysteresis, 
appliance will automatically 
jump from “H.M” modulation to 
preset output level. Thus, TR 
must have dropped to 

 194 

°C. TW must have dropped to 

 69 °C. 

 

 

TW OFF = 

 

Appliance shutdown due 
to excessive temperature 
in heat exchanger (see 
also 0Only in Waterplus 
models!
 
 
“TW OFF” and “G OFF” 
blink alternately for 
duration of fan after-run. 
Measuring point: internal 
boiler sensor (heat 
exchanger) FKY. 

 

 
This is a control function 
rather than an error. 

 

 

Control function or external error. 
 
Temperature in heat exchanger (TW) 
above desired value. 

 

 
Appliance switches from fan after-run “G 
OFF” to “TW OFF”. 

 

 
The cause is almost always external, not 
due to the appliance, since TW only 
triggers when heat generated by the 
appliance is not transmitted. This can 
happen, for ex., when the heat demand 
of a single-storey heating system without 
storage drops to zero. TW OFF then 
serves as a control function. 

 

 

TW < 85 °C 

 

 

11 K 

hysteresis

 

 

Appliance restarts 
automatically as soon as TW 
has dropped to 

 74 °C. 

 

 
If “TW OFF” occurs frequently, 
check the domestic water 
system. 

 

 

7.4  Burn-back protection  

Burn-back protection is provided by a number of mechanisms, some of which are protected by 
registered  design  or  patent  rights.  All  wodtke  appliances  are  equipped  with  a  unique  fivefold 
protection 
against burn-back into the fuel hopper, consisting of pellet chute cooling, wodtke air 
flow sensor technology, temperature cutoff (STB) and a temperature sensor in the chute. This 
goes far beyond even the most stringent legal requirements.  

7.5  wodtke air flow sensor technology  

Located  in  the  central  suction  pipe  is  an  air  flow  sensor  which  measures  the  current  air  flow 
velocity in the suction pipe, compares it with the set desired values and automatically corrects 
deviations by increasing or decreasing the speed of the flue gas fan. In this way the appliance 
automatically  adjusts  itself,  within  its  range of  control, to  changes in  chimney  draught,  internal 
resistance  (for  ex.  soiling  of  flueways  or  burner  pot)  and  varying  air  suction  resistance  and  is 
provided with an optimal air flow at all times.
