Introduction
This product is only for use with a Smiths Caspian Low Level (LL) Fan Convector.
The TCAS 12 kit will operate automatically under normal running conditions.
An adjustable room thermostat (T1) located in the incoming air provides constant
room temperature control. To provide rapid warm up the automatic speed change
thermostat (T2) switches fan(s) between 2 selected speeds at any predetermined
temperature setting (generally a difference of between 3 –6 degrees lower than that
of T1 is used). The constant temperature control is then maintained by the T1 room
thermostat.
Warning:
Isolate the power supply to the Caspian unit. Do not reconnect the power supply until
the installation has been completed.
ALL ELECTRICAL INSTALLATIONS CONNECTIONS MUST COMPLY WITH
BS7671, 1992 AND THE IEE REGULATIONS. CHECK THE VOLTAGE ON THE
HEATER IS CORRECT FOR YOUR SUPPLY. IF IN DOUBT, CONSULT A
QUALIFIED ELECTRICIAN.
