7.2.3 Initial Settings
Depending on how the thermostat is used in each individual application, its settings must be
adjusted for the relevant case.
Case 1: Controlling the room supply air temperature
To set the thermostat for controlling the room supply air temperature, perform the following
steps:
1.
Open the AHU Kit enclosure (see “4.1 Installation of AHU Kit“ – step 2).
2.
On the thermostat, switch to PID mode by entering the “Parameter” menu and set parame-
ters P, I and D to the values given below (see “7.2.2 Operation – Changing values in the
‘Parameter’ menu”).
AHU situation
P
I
D
(a) Capacity high and air volume fl ow low
7
120
3
(b) Capacity low and air volume fl ow high
3
180
10
These PID settings are intended to respond to AHU situations, where either the required
capacity is rather high (close to the upper limit of the nominal AHU kit capacity) while at the
same time the air volume fl ow is rather low (a), or vice versa (b).
If the initial PID setting results in an unstable temperature during operation, these values
may be adjusted manually at a later stage.
3. On the thermostat, switch to cooling or heating mode, depending on the AHU requirements
(for AHU Kit models equipped with thermostat TR-16, see “7.2.2 Operation – Switching from
‘heating mode’ to ‘cooling mode’”; for models with TR-16e, this procedure is not required).
