Changeover coil:
For systems equipped with CO coil integrated in the duct, the system or the module is equipped with a condensate
collector. Provision must be made for collection of condensate via a siphon.
The 3-way plate must be fixed at the water inlet before the bypass.
The 3-way valve and the changeover plate must wired up.
Connect the unit as follows:
Red wire of the plate (CO) to 10 V (Y) of the valve servomotor
Terminal
15
to +24 V (G0) of the valve servomotor
Terminal
16
to 0 V (G0) of the valve servomotor
Terminal
17
to brown wire of the plate (hot signal)
Terminal
30
to black wire of the plate (cold signal)
Connect the NF contact (C and 2) of the
THA
(antifreeze thermostat ) to
5
and
6
.
Possibility to control the operation of the circulator on terminals
DO3 of the controller and 18 of the terminal block
(higher
temperature required) and to terminals
DO4 of the controller
and
19 of the terminal block
(lower temperature required).
(Caution: the 24 V output is to be connected via a relay)
WARNING: in this case use one relay for each output and wire them in parallel to the M/A of the circulator

V.13. Direct expansion coil for cooling only or reversible coil
For systems equipped with a DX module in the duct, the supplementary module is equipped with a condensate
collector. Provision must be made for collection of condensate via a siphon.
We provide:
a 24 V output for system heating or cooling requirements
•
a 0-10 V hot output and a 0-10 V cold output.
•
Heating request:
24 V output: Connect to terminals
DO3 of the controller and 18 of the terminal block
; allows a startup signal to be
•
sent to control a DX module (Caution: max. 12V 2A to be connected via relay)
0-10 V output: Connect to terminals
15
and
16 (15 = 0 V and 16 = 0/10 V)
•
Cooling request:
24 V output: Connect to terminals
DO4 of the controller and 19 of the terminal block
; allows a startup signal to be
•
sent to control a DX module (Caution: max. 12V 2A to be connected via relay)
0-10 V output: Connect to terminals
29
and
30 (29 = 0 V and 30 = 0/10 V)
•
WARNING: If the 24 V outputs are used, use one relay for each output and wire them in parallel to the M/A of the DX
module
WARNING: The 24 V and 0-10V run commands do not provide any anti short-cycle protection for the direct
expansion coil.
IV.14. Electric heater battery
The electric heater batteries are single-phase units from 500 to 1500 and three-phase units from 2000 to 3500.
