1. INTRODUCTION<br />
The K control <strong>panel</strong> is fitted on the DE DIETRICH<br />
DTG 320 S or DTG 320 Eco.NOx boilers.<br />
2. GENERAL<br />
2.1 Overview<br />
The K control <strong>panel</strong> allows operating a 2-stage boiler<br />
(DTG 320 S or DTG 320 Eco.NOx).<br />
It may be fitted along with various optional features:<br />
- MB2 domestic hot water priority module<br />
or<br />
- SV-matic weather compensator for 2-stage burners,<br />
regulating the burner only or the burner with one mixing<br />
valve, for heating only or for heating and domestic hot<br />
water<br />
or<br />
- Cascade board (package AD 135). The cascade<br />
board is used in installations where one or more<br />
boilers (up to 9) fitted with K contol <strong>panel</strong>s are<br />
controlled by a boiler fitted with a Diematic-m Delta<br />
control <strong>panel</strong> for cascaded operation of the entire<br />
boilers system.<br />
The connection between the boilers is carried out via<br />
the 8 m long connecting cable supplied with the<br />
AD 135 package.<br />
- A 12 m long cable - package AD 134 - is available as<br />
an option if required.<br />
- Hour run meter(s) (package BG 40)<br />
- Flue gas thermometer (package BP 28).<br />
3<br />
The electrical connections of the boiler shall<br />
be performed by a qualified professionnal<br />
only.<br />
Strict compliance with these connecting,<br />
starting up and operating instrucions is a<br />
precondition for the correct operation of the<br />
boiler.
2.2 Description<br />
2 allures<br />
1. Three-position switch Auto / Manual / STB TEST<br />
1.1 Boilers fitted with a cascade board<br />
(package AD 135)<br />
11 8 9 1 10 13 6<br />
AUTO: automatic position<br />
This position allows automatic operation of the<br />
installation under the control of the Diematic-m<br />
Delta regulator.<br />
Manual : manual position<br />
The boiler disregards the commands coming<br />
from the cascade board. It is regulated by the<br />
boiler thermostats (item 5)<br />
1.2 Other cases<br />
- either in manual position : boilers not fitted<br />
with a room thermostat or a SV-matic weather<br />
compensator.<br />
- or in AUTO position: boilers fitted with a room<br />
thermostat or a SV-matic weather compensator.<br />
The manual position does not allow<br />
switching off the regulator.<br />
STB Test: temporary action to test the safety<br />
thermostat:<br />
Press the TEST STB switch and set the pump shutoff<br />
switch 2 to the "Summer" position.<br />
2. Double switch Burner/Heating pump:<br />
This double switch controls the burner and the<br />
heating pump.<br />
In the "Winter" position, both heating and<br />
domestic hot water are operating.<br />
In the "Summer" position, only domestic hot water<br />
is operating (if a hot water tank is connected).<br />
If the boiler is fitted with a SV-matic weather<br />
compensator or is part of a cascaded installation,<br />
both switches must be left on the Winter<br />
position.<br />

2.3 Operating principle<br />
Boiler regulation<br />
Boiler regulation may be performed:<br />
- either by the boiler thermostats,<br />
- or by the SV-matic weather compensator, if any<br />
(optional),<br />
- or by the DIEMATIC-m Delta control <strong>panel</strong> in case of<br />
a cascaded installation.<br />
If the boiler is fitted with a SV-matic weather compensator<br />
or is controlled by a DIEMATIC-m Delta control<br />
<strong>panel</strong>, the boiler temperature is modulated by the<br />
regulator acting on the burner according to the outside<br />
temperature. In this case, the boiler thermostats are set<br />
to the maximum position. Operating safety is provided<br />
by the safety thermostat with manual reset.<br />
If the boiler is fitted with a SV-matic weather compensator<br />
controlling a valve, the heating temperature is<br />
modulated by the regulator acting on the burner and on<br />
the motorised mixing valve according to the outside<br />
temperature.<br />
For a cascaded installation controlled by a boiler fitted<br />
with a DIEMATIC-m Delta control <strong>panel</strong>, refer to the<br />
instructions supplied with the DIEMATIC-m Delta control<br />
<strong>panel</strong>.<br />
5<br />
Domestic hot water regulation<br />
With the optional MB2 domestic hot water priority<br />
module or the Type B SV-matic weather compensator:<br />
When the domestic hot water is being reheated, the<br />
burner and the load pump are started while the<br />
heating pump is stopped. The boiler temperature is<br />
then regulated by the limiter thermostat integrated in<br />
the MB2 module or in the SV-matic weather compensator.<br />
Once the need for hot water is met, the burner is<br />
turned off. The load pump continues operating for 4<br />
minutes after the burner stops (This delay is adjustable<br />
from 30 sec to 15 min). This allows using the residual<br />
heat accumulated in the heating elements and complete<br />
heating the tank, especially in summer.<br />
For a cascaded installation controlled by a boiler fitted<br />
with a DIEMATIC-m Delta control <strong>panel</strong>, refer to the<br />
instructions supplied with the DIEMATIC-m Delta control<br />
<strong>panel</strong>.
3. ELECTRICAL CONNECTIONS<br />

5. START-UP AND OPERATION<br />
5.1 <strong>Control</strong> <strong>panel</strong> without optional features<br />
The initial start-up shall be performed by<br />
a qualified professionnal.<br />
Before turning the boiler on, make sure that the<br />
installation is filled with water.<br />
Carry out the start-up operations in the order<br />
indicated below:<br />
● Boiler temperature regulation by means of the<br />
thermostats<br />
Set the boiler thermostats 5 to the selected position.<br />
In case of a two-stage burner, the stage 2 thermostat<br />
must always be set to a value which is approximately 5°C<br />
less than that of the stage 1 thermostat.<br />
If required, move the maximum temperature stop as shown<br />
below.<br />
Moving the thermostat stop:<br />
The stop is factory-set to limit the maximum temperature<br />
to 75°C. To move the stop, proceed as follows:<br />
- Pull the thermostat button out.<br />
- Remove the stop using pliers.<br />
- Place the stop in the hole corresponding to the<br />
desired higher temperature (maximum 90°C).<br />

If there is no regulator, it is advised never<br />
to set the boiler thermostats below mark<br />
4 (approximately 40°C) in order to avoid<br />
any risk of combustion products condensing<br />
on the walls of the boiler.<br />
● Set switch 1 to the manual position .<br />
