- One Thermostat: Brand Unknown
- Remote Alarm Module: Brand unknown

- Form the Thermostat to AC unit :
c to c
R to R
Y1 to Y1
Y2 to Y2
G to G

- From Smoke Detector to AC Unit
6 to R
17 to SD
(6-17) is aux contact in D4120

From Same thermostat to The electric Heater
I see only 3 contact in Heater :
T1 : 0-10VDC

How can I can connect it to the same thermostat?

Also I need a sample Remote Alarm Module to connect it directly to Smoke detector and how
