You sure that is a heater and not an ionisation module?

[kefah]

im really not sure
but if we assume its electric heater
what its for

[install monkey]

ioniser...
look at the nameplate for electrical load- prob around 50watt for fan motor and comms- if it was a heater then it would be of a higher output

smoke removal

ok
is there any wall amount heat pump contain electric heater in indoor unit or not

mitsubishi mr slims about 10yr ago used to have a boost heater option
imi hilo units had elec htr but theyre 20 yr old
any electric heater will affect energy efficiency ratings- also a fire hazard too- burgerkings used to use york ducted units with electric reheat batteries in the duct - lots of flashy lights when a 90kw 3ph heater bank blows an element

on imi's they were for heating as reverse cycle heating in low ambients meant regular defrosting , on mitsi units they were an option to boost output -in cooling mode on any air con then the indoor shouldnt freeze up if aslong as the filters clean,setpoint is within limits and gas charge is ok
