Case 2: Adjusting the temperature setpoint based on ambient air
temperature
To set the thermostat for adjusting the temperature setpoint based on ambient air temperature
(T
out
), perform the following steps:
1. Open the AHU Kit enclosure (see →
4.1.1 Installation of AHU Kit – MAH2/PAH2 – step 3,
p. 48
).
2. On the thermostat, switch to PID mode by entering the “Parameter” menu and setting
parameters P, I and D to the values given below (see →
7.2.2 Thermostat – Operation –
Changing values in the “Parameter” menu, p. 103
):
P ≠ 0 (not zero)
I = 0 (zero)
D = 0 (zero)
The value of parameter P represents the required gradient for the cooling or heating curve in
modulating temperature control (see diagrams below) and must not be equal to zero.
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 Thermostat – Operation –
Switching from “heating mode” to “cooling mode”, p. 105 ; for models with TR-16e, this
procedure is not required).
4. On the thermostat, change the set temperature value as required (see →
7.2.2 Thermostat –
Operation – Changing the set temperature value, p. 102
).
In this case, the set temperature value represents the adjusted temperature setpoint based on
ambient air temperature (T
set TR-16
), beyond which any cooling or heating operation is stopped
(heating or cooling limit temperature).
5. On the remote controller (CZ-RTC5B), set the upper and lower limits for the adjusted
temperature setpoint in cooling or heating mode.
Inbetween the upper and lower limit the setpoint will be adjusted in a linear way (see diagrams
below).
Mode Parameter name
For upper limit For lower limit
Cooling Parameter “1F” Parameter “20”
Heating Parameter “21” Parameter “22”
This setting together with the value of parameter P defines the cooling or heating ramp curve as
shown in the following diagrams.

6. Remove the AHU Kit’s upper mounting board.
7. On the CZ-CAPBC2 PCB (ACC-SP1A), located on the rear side of the upper mounting board
inside the AHU Kit enclosure, make sure that switches S1 to S4 are set as follows:
