Instruction Manual

The ASR–ZW receiver unit receives the Z-Wave radio signals from the

HRT4–ZW room thermostat. In the unlikely event of a communication failure it

is possible to override the system and switch On and Off using the On/Off

buttons on the ASR-ZW receiver as a local override.

If the override is used to override the HRT4-ZW thermostat when it is

functioning correctly then the override will be cancelled by the next switching

operation of the thermostat and normal operation will be resumed. In any case,

with no further intervention, normal operation will be restored within one hour

of the override being operated.
